The current API version is Versapay API Reference (1.3.21).

Versapay commits to maintaining backward compatibility and existing API endpoints with each released version updating existing endpoints and/or introducing new endpoints.

Should Versapay require deprecation of a published API, Versapay will work with its API clients/users to confirm specific EOL/migration timelines with ample lead times, as well as endpoint migration strategies.

The UAT environment is a useful sandbox for integration testing where transaction settlements are simulated using test account numbers and test dollar amounts.

Once integration testing is complete via the UAT environment, start sending your requests to the production URL to start moving money and/or integrating with Versapay.

The standard rate limit is 1500 requests per minute per IP address, but Versapay reserves the right to raise or lower that limit based on network conditions. When the rate limit is exceeded, APIs will return error HTTP 1015 you are being rate limited. Partner- or customer-specific rate limits can be established by special agreement.

Visit your account settings in UAT (https://uat.versapay.com/account) or Production (https://secure.versapay.com/account) to setup API credentials needed for authentication as well as webhooks to receive relevant callbacks from Versapay transaction processing.

You can generate/disable your API credentials as often as necessary for security reasons.

If you do not have an account, please contact Versapay Support for support & setup of AR invoicing integration, hosted checkout and/or payment acceptance for partner and/or API credential setup.

curl -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbiI6Im54eDFaSjgzeXRNNmhtb3NGVExCIiwiZXhwIjoxNzEyOTU5NDA5fQ.adV6U1vW69Ypskt61uPL8hZ-4muvtM4FLM48QN6iCc4" -X POST https://secure.versapay.com/api/...
