Plastiq Connect APIs are exposed as a public web service/API that is secured by communication encryption via transport layer security, client IP address restriction, and API user credentials.

How to Authenticate with Plastiq Connect

Plastiq Connect authenticates all of your API calls using your partner API Key and IP address.

The steps to authenticate with Plastiq Connect are as follow:

  1. You will provision separate keys for your sandbox and production environments
  2. You will update an IP Allowlist with approved IP addresses in each environment

An API Key provisioned for Sandbox will not be usable in Production and vice-versa.

Usage of the Plastiq Connect UI widget requires a Client Secret, which is generated using your API Key and a Payer Id.


Client Secrets

A Client Secret is a one-time use token that is specific to a Payer and the Payment information they have entered.
