Get Started with API People APIs

This guide provides a step-by-step checklist to connect your systems with API People APIs. You will learn how to request access, configure your environment with mTLS, and make your first successful API call to verify your setup.

Onboarding Overview​

The onboarding process involves three key phases: you submit a request, our team provisions your credentials, and you verify the connection.

Step 1: Request API Access​

To begin, contact our team trough the Contact Us form.

Please include the following information in your message:

  • APIs Needed: Specify which APIs you need (e.g., ACH Payments, Wire Payments, Statements).
  • Business Name: Your official business name.
  • Technical Contact: Name and email of the primary developer or team lead.
Turnaround Time

Please allow 1-2 business days for our team to process your request and provision your credentials.

Step 2: Receive Your Credentials​

Once your request is approved and your certificate is configured, the API People team will securely provide your unique OAuth 2.0 credentials:

  • client_id
  • client_secret

Store these credentials in a secure location, such as a managed secrets vault. You will use them in the next step to generate a bearer token for your API calls.

Step 3: Verify Your Connection with a Test Call​

Before integrating with production endpoints, verify that your credentials and mTLS setup are working correctly. You can do this by calling the simple and secure Hello API People API.

This single test confirms your entire setup:

  • Your mTLS certificate is accepted.
  • Your client_id and client_secret can be used to generate a valid access token.
  • Your request headers are correctly formatted.

First, use your credentials to get a bearer token from our OAuth 2.0 API. The response will contain your access_token. After, use that token to call the Hello API People API.

A successful 200 OK response with a confirmation message means your setup is correct and you are ready to start building. If you receive an error, check the Error Codes page for troubleshooting guidance.

What’s Next?​

With your connection verified, you are ready to integrate. We recommend reviewing the following documentation to ensure a robust and secure implementation.
