Solid APIs are REST-based and built around JSON-encoded requests and responses with standard authentication method, response and error codes. To get started,
  1. Solid team will set you up with a Pre-provisioned Sandbox account.
  2. Using the Dashboard in the Sandbox environment, you’ll create an API key.
You’ll need Postman or a similar tool to run the APIs.
You always start with a Sandbox. Once your FinTech program is ready to be onboarded with the partner bank, you’ll receive a pre-provisioned Production access.
Here are the ten steps we will guide you through. After completing these steps, you will have originated a sub account, created cards and counterparties, made a payment and viewed the transactions.
