# Stripe Source Connector for Confluent Cloud The fully managed Stripe Source connector for Confluent Cloud reads records from Stripe resources, such as charges, customers, invoices, and subscriptions, and streams them to Kafka topics. On first start, the connector loads records created at or after a start timestamp that you set, and then continuously captures new records and changes from Stripe events. #### NOTE If you require private networking for fully managed connectors, make sure to set up the proper networking beforehand. For more information, see [Manage Networking for Confluent Cloud Connectors](../networking/internet-resource.md#clusters-connect-cloud). ## Features The Stripe Source connector provides the following features: * **Supported resources**: Reads up to 29 Stripe resources, including accounts, application fees, balance transactions, charges, checkout sessions, coupons, credit notes, customers, disputes, events, invoices, payment intents, payouts, plans, prices, products, refunds, setup intents, subscriptions, and transfers. Select up to seven resources per connector in the `stripe.resources property`, using their Stripe API names, for example `balance_transactions`. * **Initial load and change capture**: On first start, the connector copies every record created at or after `stripe.initial.start.timestamp`. After that, it keeps polling Stripe for new records and reads changes from Stripe events. * **Topic routing**: Writes each resource’s records to ``, for example `stripe-charges`. For most resources, the connector also writes that resource’s Stripe events, such as `customer.created`, `customer.updated`, and `customer.deleted`, to `_events`. * **Authentication**: Authenticates with a Stripe secret key (`sk_...`) or restricted key (`rk_...`). The key determines whether the connector reads sandbox or live mode data. Confluent recommends that you use a restricted key. * **Connected accounts**: Reads one connected account’s data through your platform’s API key. Set `stripe.connected.account.id` to the account’s `acct_...` ID. * **Data formats**: Writes Avro, JSON Schema (JSON_SR), or Protobuf records with Schema Registry. With Avro, and with JSON_SR configured as described in the [limitations](../limits.md#cc-stripe-source-limits), fields that Stripe adds later are added to the topic’s schema automatically in the default EVOLVE schema mode. [Schema Registry](../../get-started/schema-registry.md#cloud-sr-config) must be enabled to use these formats. For the record value schema of each resource and its events topic, see [Stripe Source Connector Record Schemas](stripe-source-record-schemas.md#cc-stripe-source-record-schemas). * **At least once delivery**: The connector supports at least once delivery. After a restart or a pause, the connector continues from where it stopped. Custom offset management lets you load a resource again from the start timestamp. For more information, see [Manage custom offsets](#cc-stripe-source-custom-offsets). For more information and examples to use with the Confluent Cloud API for Connect, see the [Confluent Cloud API for Connect Usage Examples](../connect-api-section.md#ccloud-connect-api) section. ## Limitations Be sure to review the following information. * For connector limitations, see [Stripe Source Connector](../limits.md#cc-stripe-source-limits) limitations. * If you plan to use one or more Single Message Transforms (SMTs), see [SMT Limitations](../single-message-transforms.md#cc-single-message-transforms-limitations). With the default `EVOLVE` schema mode, avoid SMTs that add, remove, rename, or retype a field. For details, see [Schema evolution](../cc-http-source-v2.md#cc-http-source-v2-schema-evolution). * If you plan to use Confluent Cloud Schema Registry, see [Limits for Fully Managed Connectors for Confluent Cloud](../limits.md#connect-ccloud-limits). ## Manage custom offsets You can manage the offsets for this connector. Offsets provide information on the point in the system from which the connector is accessing data. For more information, see [Manage Offsets for Fully Managed Connectors in Confluent Cloud](../offsets.md#connect-custom-offsets). **To manage offsets**: - Manage offsets using Confluent Cloud APIs. For more information, see [Connect offsets API reference](https://docs.confluent.io/cloud/current/ccloud/offsets-connect-v-1/). If a task fails because the last record the connector read for a resource is deleted at Stripe, or because the last event it read is older than Stripe’s 30-day event retention, update that resource’s offset to recover. For more information about this failure, see [Stripe Source Connector](../limits.md#cc-stripe-source-limits). ## Quick Start Use this quick start to get up and running with the Confluent Cloud Stripe Source connector. The quick start provides the basics of selecting the connector and configuring it to stream events from Stripe resources to Kafka topics. Prerequisites : - Authorized access to a [Confluent Cloud](https://www.confluent.io/confluent-cloud/) cluster on Amazon Web Services (AWS), Microsoft Azure (Azure), or Google Cloud. - The Confluent CLI installed and configured for the cluster. See [Install the Confluent CLI](https://docs.confluent.io/confluent-cli/current/install.html). - [Schema Registry](../../get-started/schema-registry.md#cloud-sr-config) must be enabled to use a Schema Registry-based format (for example, Avro, JSON_SR (JSON Schema), or Protobuf). For more information, see [Limits for Fully Managed Connectors for Confluent Cloud](../limits.md#connect-ccloud-limits). - A Stripe account with a secret key (`sk_...`) or restricted key (`rk_...`). Confluent recommends that you use a restricted key with read access to each resource you select, and to events for resources that have an `_events` topic. - For networking considerations, see [Networking and DNS](../overview.md#connect-internet-access-resources). To use a set of public egress IP addresses, see [Public Egress IP Addresses for Confluent Cloud Connectors](../static-egress-ip.md#cc-static-egress-ips).
- Kafka cluster credentials. The following lists the different ways you can provide credentials. - Enter an existing [service account](../service-account.md#s3-cloud-service-account) resource ID. - Create a Confluent Cloud [service account](../service-account.md#s3-cloud-service-account) for the connector. Make sure to review the ACL entries required in the [service account documentation](../service-account.md#s3-cloud-service-account). Some connectors have specific ACL requirements. - Create a Confluent Cloud API key and secret. To create a key and secret, you can use [confluent api-key create](https://docs.confluent.io/confluent-cli/current/command-reference/api-key/confluent_api-key_create.html) *or* you can autogenerate the API key and secret directly in the Cloud Console when setting up the connector. ### Using the Confluent Cloud Console #### Step 1: Launch your Confluent Cloud cluster To create and launch a Kafka cluster in Confluent Cloud, see [Create a kafka cluster in Confluent Cloud](../../get-started/index.md#cloud-create-kafka-cluster). #### Step 2: Add a connector In the left navigation menu, click **Connectors**. If you already have connectors in your cluster, click **+ Add connector**. #### Step 3: Select your connector Click the **Stripe Source** connector card. #### Step 4: Enter the connector details #### NOTE * Ensure you have all your [prerequisites](#cc-stripe-source-prereqs) completed. * An asterisk ( \* ) designates a required entry. At the **Add Stripe Source Connector** screen, complete the following: ### Kafka credentials 1. Select the way you want to provide **Kafka Cluster credentials**. You can choose one of the following options: - **My account**: This setting allows your connector to globally access everything that you have access to. With a user account, the connector uses an API key and secret to access the Kafka cluster. This option is not recommended for production. - **Service account**: This setting limits the access for your connector by using a [service account](../service-account.md#s3-cloud-service-account). This option is recommended for production. - **Use an existing API key**: This setting allows you to specify an API key and a secret pair. You can use an existing pair or create a new one. This method is not recommended for production environments. #### NOTE Freight clusters support only service accounts for Kafka authentication. 2. Click **Continue**. ### Authentication 1. Configure the authentication properties: **Authentication** - **Stripe API key**: Your Stripe secret key or restricted key. Confluent recommends a restricted key with read access to the resources you select and to events. A sandbox key reads sandbox data, and a live mode key reads live data. - **Connected account ID**: Leave this blank to read your own Stripe account, or enter a connected account ID, such as `acct_1Nv0FGQ9RKHgCVdK`, to read that account instead. Each connector reads one account, so create one connector per connected account. 2. Click **Continue**. ### Configuration #### NOTE Configuration properties that are not shown in the Cloud Console use the default values. For all property values and definitions, see [Configuration Properties](#cc-stripe-source-config-properties). **Output messages** - **Select output record value format**: Output Kafka record value format. Valid entries are `AVRO`, `JSON_SR`, or `PROTOBUF`. Set up Confluent Cloud Schema Registry for these schema-based message formats. With `PROTOBUF`, set the schema evolution mode to `NONE`. **Stripe resources** - **Stripe resources to sync**: The Stripe resources to sync, up to seven per connector. To sync more, create another connector. - **Load data created since**: Load records created at or after this time, as a Unix timestamp in seconds. `0` loads all history. Stripe keeps change events for 30 days, so older changes are not loaded. ### **Show advanced configurations** - **Reporter Error Topic Name**: The name of the topic to produce errant records after each unsuccessful API operation. Defaults to `error-${connector}` if not set. You can provide `${connector}` in the value to use it as a placeholder for the logical cluster ID. - **Schema context**: Select a schema context to use for this connector, if using a schema-based data format. This property defaults to the **Default** context, which configures the connector to use the default schema set up for Schema Registry in your Confluent Cloud environment. A schema context allows you to use separate schemas (like schema sub-registries) tied to topics in different Kafka clusters that share the same Schema Registry environment. For example, if you select a non-default context, a **Source** connector uses only that schema context to register a schema and a **Sink** connector uses only that schema context to read from. For more information about setting up a schema context, see [What are schema contexts and when should you use them?](../../sr/faqs-cc.md#faq-schema-contexts). **Polling configurations** - **Poll Interval (ms)**: How long, in milliseconds, the connector waits between requests to Stripe for each resource. This also sets how fast history loads, one page of up to `100` records per interval. Lower values load history faster and deliver changes sooner, but use more of your Stripe API rate limit and read allocation. **Additional Configs** - **Value Converter Decimal Format**: Specifies the `JSON` or `JSON_SR` serialization format for Connect `DECIMAL` logical type values with two allowed literals: `BASE64` to serialize `DECIMAL` logical types as base64 encoded binary data, and `NUMERIC` to serialize `DECIMAL` logical type values in `JSON` or `JSON_SR` as a number representing the decimal value. - **Key Converter Schema ID Serializer**: The class name of the schema ID serializer for keys. This is used to serialize schema IDs in the message headers. - **Value Converter Reference Subject Name Strategy**: Sets the subject reference name strategy for values. Valid entries are `DefaultReferenceSubjectNameStrategy` or `QualifiedReferenceSubjectNameStrategy`. You can use this strategy only with `PROTOBUF` format; the default strategy is `DefaultReferenceSubjectNameStrategy`. - **Errors Tolerance**: Use this property to configure the connector’s error handling behavior. #### WARNING Use this property with caution for sink connectors, as it can lead to data loss. If you set this property to `all`, the connector does not fail on errant records, but logs them (and sends to DLQ for sink connectors) and continues processing. If you set this property to `none`, the connector task fails on errant records. - **Value Converter Connect Meta Data**: Enables the Connect converter to add its metadata to the output schema. Applies to Avro converters. - **Value Converter Value Subject Name Strategy**: Determines how to construct the subject name under which the value schema is registered with Schema Registry. - **Key Converter Key Subject Name Strategy**: Determines how to construct the subject name for key schema registration. - **Value Converter Ignore Default For Nullables**: When set to `true`, this property ensures that the corresponding record in Kafka is `null`, instead of showing the default column value. Applies to the `AVRO`, `PROTOBUF`, and `JSON_SR` converters. - **Value Converter Schema ID Serializer**: The class name of the schema ID serializer for values. This is used to serialize schema IDs in the message headers. **Auto-restart policy** - **Enable Connector Auto-restart**: Enables the auto-restart behavior of the connector and its task in the event of user-actionable errors. Defaults to `true`, enabling the connector to automatically restart in case of user-actionable errors. Set this property to `false` to disable auto-restart for failed connectors. If disabled, you must manually restart the connector. **Output messages** - **Schema evolution mode**: How the connector handles a field that Stripe returns but the connector does not know. `EVOLVE` adds it to the topic’s schema once, with its detected type. `NONE` adds it as an optional string, only in the records that carry it. With `PROTOBUF`, use `NONE`. **Transforms** - **Single Message Transformations**: To add a new SMT, see [Add transforms](../single-message-transforms.md#cc-single-message-transforms-ui). For more information about unsupported SMTs, see [Unsupported transformations](../single-message-transforms.md#cc-single-message-transforms-unsupported-transforms). For all property values and definitions, see [Configuration Properties](#cc-stripe-source-config-properties). - Click **Continue**. ### Sizing Based on the number of resources you select, the connector recommends a number of tasks. 1. To change the number of recommended tasks, enter the number of [tasks](/platform/current/connect/concepts.html#tasks) for the connector to use in the **Tasks** field. 2. Click **Continue**. ### Review and Launch 1. Verify the connection details. 2. Click **Launch**. The status for the connector should go from **Provisioning** to **Running**. #### Step 5: Check for records Verify that records are populating the Kafka topics. Each selected resource writes its records to ``, for example `stripe-charges`, and, for most resources, writes that resource’s Stripe events to `_events`. For more information and examples to use with the Confluent Cloud API for Connect, see the [Confluent Cloud API for Connect Usage Examples](../connect-api-section.md#ccloud-connect-api) section. ### Using the Confluent CLI Complete the following steps to set up and run the connector using the Confluent CLI. #### NOTE Make sure you have all your [prerequisites](#cc-stripe-source-prereqs) completed. #### Step 1: List the available connectors Enter the following command to list available connectors: ```none confluent connect plugin list ``` #### Step 2: List the connector configuration properties Enter the following command to show the connector configuration properties: ```none confluent connect plugin describe ``` The command output shows the required and optional configuration properties. #### Step 3: Create the connector configuration file Create a JSON file that contains the connector configuration properties. The following example shows required and optional connector properties. ```none { "name": "StripeSource_0", "config": { "connector.class": "StripeSource", "name": "StripeSource_0", "kafka.auth.mode": "KAFKA_API_KEY", "kafka.api.key": "", "kafka.api.secret": "", "stripe.api.key": "", "stripe.resources": "charges, customers, invoices", "stripe.initial.start.timestamp": "", "topic.prefix": "stripe-", "output.data.format": "JSON_SR", "value.converter.object.additional.properties": "false", "tasks.max": "1" } } ``` Note the following property definitions: * `"name"`: Sets a name for your new connector. * `"connector.class"`: Identifies the connector plugin name. * `"stripe.api.key"`: Your Stripe secret key (`sk_...`) or restricted key (`rk_...`). The key determines whether the connector reads sandbox or live mode data. * `"stripe.resources"`: A comma-separated list of Stripe resources to read, identified by their Stripe API names, for example `balance_transactions`. * `"stripe.initial.start.timestamp"`: How far back to load history, as a Unix timestamp in seconds. The connector loads everything created at or after this instant, and then follows changes from that point on. * `"topic.prefix"`: The prefix for the Kafka topics of every selected resource. With the default, `stripe-`, charges are written to `stripe-charges` and their changes to `stripe-charges_events`. * `"output.data.format"`: Sets the output Kafka record value format. Valid entries are `AVRO`, `JSON_SR`, or `PROTOBUF`. * `"value.converter.object.additional.properties"`: With JSON_SR, the default output format, set this property to `false` when you create the connector. Otherwise, the connector stops when Stripe adds a field to a selected resource. * `"kafka.auth.mode"`: Identifies the connector authentication mode you want to use. There are two options: `SERVICE_ACCOUNT` or `KAFKA_API_KEY` (the default). To use an API key and secret, specify the configuration properties `kafka.api.key` and `kafka.api.secret`, as shown in the example configuration (above). To use a [service account](../service-account.md#s3-cloud-service-account), specify the **Resource ID** in the property `kafka.service.account.id=`. To list the available service account resource IDs, use the following command: ```bash confluent iam service-account list ``` For example: ```bash confluent iam service-account list Id | Resource ID | Name | Description +---------+-------------+-------------------+------------------- 123456 | sa-l1r23m | sa-1 | Service account 1 789101 | sa-l4d56p | sa-2 | Service account 2 ``` * `"tasks.max"`: Maximum [tasks](/platform/current/connect/concepts.html#tasks) for the connector to use. Set it to a value no greater than the number of selected resources. See [Configuration Properties](#cc-stripe-source-config-properties) for all property values and descriptions. #### Step 4: Load the configuration file and create the connector Enter the following command to load the configuration and start the connector: ```none confluent connect cluster create --config-file .json ``` For example: ```none confluent connect cluster create --config-file stripe-source-config.json ``` Example output: ```none Created connector StripeSource_0 lcc-ix4dl ``` #### Step 5: Check the connector status Enter the following command to check the connector status: ```none confluent connect cluster list ``` Example output: ```none ID | Name | Status | Type +-----------+---------------------+---------+--------+ lcc-ix4dl | StripeSource_0 | RUNNING | source ``` #### Step 6: Check for records Verify that records are populating the Kafka topics for the resources you selected. For more information and examples to use with the Confluent Cloud API for Connect, see the [Confluent Cloud API for Connect Usage Examples](../connect-api-section.md#ccloud-connect-api) section. ## Configuration Properties Use the following configuration properties with the fully-managed connector. For self-managed connector property definitions and other details, see the connector docs in [Self-managed connectors for Confluent Platform](/platform/current/connect/kafka_connectors.html). ### How should we connect to your data? `name` : Sets a name for your connector.
