ACH Pro API
This API gives you full access to all of the features available in the ACH Pro application. The API is only available in the Ultimate plan. You will need an API key and secret which you can create by going to your Account Settings page (see Getting Started).
Authentication
All API endpoints (except /token and /token/refresh) require a bearer token: Authorization: Bearer {token}.
To create an access token, you send an API key and secret to /token. Access tokens expire in 60 minutes. They are accompanied by a refresh token which expires in 12 hours and is used to
retrieve a new access_token from /token/refresh. Once the refresh token expires,
you must call /token again using your API key and secret. The goal of this architecture is to limit the number of requests that contain your long lived API credentials.
You should create a mechanism for caching the access token and refreshing it periodically
using the refresh token.
POSTAccess Token
Exchange an API key and secret for a short-lived access_token and refresh_token.
access_expires and refresh_expires are future timestamps that indicate when their respective tokens expire.
POSTRefresh Token
Exchange a refresh token for a new short-lived access token.
Note: refresh_token and refresh_expires in the response will be the same until/token is called again and a new access token generated.
