OAuth Token Management System with Airtable Storage

This n8n workflow provides a robust system for managing OAuth tokens, leveraging Airtable as a storage backend. It allows for manual triggering to initiate the token generation or refresh process and includes logic to handle the API requests and responses.

What it does

This workflow simplifies the process of obtaining and managing OAuth tokens by:

1. Triggering Manually: The workflow can be initiated manually, which is useful for testing or for scenarios where manual intervention is desired to start the token process.
2. Making HTTP Requests: It performs an HTTP request, likely to an OAuth provider's token endpoint, to obtain or refresh an access token.
3. Conditional Logic: It includes an 'If' node to introduce conditional logic, allowing the workflow to branch based on the outcome of previous steps (e.g., success or failure of the token request).
4. Responding to Webhooks: Although the primary trigger is manual, the presence of a 'Respond to Webhook' node suggests it might be part of a larger system where it could respond to external calls, possibly for status updates or error notifications.
5. Storing Data in Airtable: It interacts with Airtable, indicating that it's designed to store or retrieve token-related data (e.g., access tokens, refresh tokens, expiration times) in an Airtable base.
6. Custom Code Execution: A 'Code' node is included, allowing for custom JavaScript logic to be executed. This could be used for data manipulation, token parsing, or more complex conditional checks before storing data or making further requests.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to import and execute the workflow.
• Airtable Account: An Airtable account with a base and table configured to store your OAuth token information. You will need an API key and the Base ID/Table Name.
• OAuth Provider: Access to an OAuth provider (ee.g., Google, Salesforce, etc.) from which you intend to obtain tokens. You'll need the appropriate client ID, client secret, and authorization endpoints.
• HTTP Request Credentials: Depending on your OAuth provider, you might need specific HTTP request credentials (e.g., API keys, basic authentication).

Setup/Usage

1. Import the Workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Airtable Credentials:
   • Locate the "Airtable" node.
   • Add or select your Airtable API Key credential.
   • Configure the Base ID and Table Name where your token data will be stored.
3. Configure HTTP Request:
   • Locate the "HTTP Request" node.
   • Set up the URL, HTTP method (e.g., POST), headers, and body according to your OAuth provider's token endpoint specifications. This will typically involve sending your client_id, client_secret, grant_type, and potentially a code or refresh_token.
   • Configure any necessary authentication for the HTTP request.
4. Configure Custom Code (if applicable):
   • Examine the "Code" node. If it contains placeholder code, adjust it to process the HTTP response, extract the token, and prepare data for Airtable storage.
5. Adjust Conditional Logic:
   • Review the "If" node. Modify its conditions to properly handle success and failure scenarios from your HTTP request, or to route data based on specific token properties.
6. Activate the Workflow: Once configured, activate the workflow.
7. Execute Manually: Click the "Execute workflow" button on the "When clicking ‘Execute workflow’" node to run the workflow manually. This will initiate the token process.

This workflow provides a flexible foundation for managing OAuth tokens, allowing for customization to fit various OAuth providers and storage requirements.
