Overview

This node processes payments through the E-Mola payment system, a mobile money service. It validates phone numbers and payment amounts before sending a payment request to the E-Mola API. The node is useful for automating mobile money transactions in workflows, such as paying suppliers, transferring funds, or collecting payments from customers.

Typical use cases include:

  • Sending payments to E-Mola users by specifying their phone number and amount.
  • Automating transaction references or providing custom references.
  • Integrating E-Mola payments into larger business automation pipelines.

Properties

Name Meaning
Phone Number E-Mola phone number (9 digits, must start with 86 or 87). Example: "861234567"
Amount Payment amount in Mozambican Metical (MZN), between 1 and 1,250,000
Reference Transaction reference string; if left empty, the node generates one automatically

Output

The node outputs an array of JSON objects, each representing the result of a payment attempt. Each output item contains:

  • success: Boolean indicating if the payment was successful.
  • provider: Always "emola" to identify the payment provider.
  • reference: The transaction reference used.
  • phone: The validated phone number used for payment.
  • amount: The payment amount sent.
  • timestamp: ISO string timestamp of when the payment was processed.
  • response: The raw response object returned from the E-Mola API on success.
  • error (only on failure): Error message describing what went wrong.

If the node is configured to continue on failure, failed attempts will still produce output items with success: false and an error message.

Dependencies

  • Requires credentials containing:
    • Base URL of the E-Mola API.
    • Client ID and Client Secret for OAuth2 authentication.
    • Wallet ID associated with the E-Mola account.
  • The node performs two HTTP POST requests:
    1. To obtain an OAuth2 access token.
    2. To submit the payment request using the access token.
  • Proper network connectivity to the E-Mola API endpoints is required.

Troubleshooting

  • Invalid phone number errors: The phone number must be exactly 9 digits and start with 86 or 87. Remove any non-digit characters before input.
  • Amount validation errors: Ensure the amount is a number between 1 and 1,250,000 MZN.
  • Authentication failures: Check that the provided client ID, client secret, and base URL are correct and that the API credentials have proper permissions.
  • API token errors: If the node cannot retrieve an access token, verify the OAuth credentials and network access.
  • Unexpected API responses: Inspect the raw response field in the output for details. Network issues or API changes may cause failures.
  • Enable "Continue On Fail" in the node settings to allow processing multiple items even if some fail.
