A2AInstall

Overview

This node interacts with an Account-to-Account (A2A) transfer service, focusing on account management and transaction retrieval. Specifically, the Get Transactions operation under the Account resource fetches a list of transactions for a specified account within an optional date range and up to a defined limit.

Typical use cases include:

• Retrieving recent or historical transaction data for reconciliation or reporting.
• Monitoring account activity over a specific period.
• Integrating transaction data into financial dashboards or workflows.

For example, a user might want to pull all transactions from their business account between January 1st and March 31st, limiting the results to the most recent 100 transactions.

Properties

Output

The output is a JSON array where each item represents a transaction associated with the specified account. Each transaction object typically includes details such as transaction amount, currency, date, description, and status (though exact fields depend on the external API response).

No binary data output is produced by this operation.

Dependencies

• Requires an API key credential and secret configured in n8n to authenticate requests against the A2A service.
• The node makes HTTP requests to the base URL provided in the credentials.
• The execute() method uses authenticated HTTP GET requests to the endpoint /accounts/{accountId}/transactions with query parameters for filtering.

Troubleshooting

• Invalid Account ID: If the account ID is incorrect or does not exist, the API may return an error or empty result. Verify the account ID before running the node.
• Date Format Issues: Ensure that the Start Date and End Date are valid ISO 8601 datetime strings. Invalid dates may cause request failures.
• Transaction Limit Too Low or High: The limit must be at least 1. Setting it too high might lead to timeouts or large payloads; adjust accordingly.
• Authentication Errors: If the API key or secret is missing or invalid, authentication will fail. Confirm credentials are correctly set in n8n.
• API Rate Limits: Frequent calls may hit rate limits imposed by the external service. Implement retry logic or reduce call frequency if needed.
