When you're ready to test and integrate your project, our API Onboarding team can help you get access to our APIs in a higher test environment. Before we move your solution to our UAT environment you’ll need to complete the following steps:

 1. [Verify](/dashboard) your organization to get started with an API product.

 2. Submit an [API onboarding support ticket](/support/create) to request API keys to our testing environment.

 3. Work with your relationship manager and sales team to complete any contractual agreements and product setup, if necessary.

 4. Complete the Mutual Transport Layer Security (mTLS) certification requirements found in the API’s security guide.

 5. Work with the API Onboarding team for API setup.

 The API Onboarding team will send you an email with details on how to complete these steps.

 

During testing our API Integration team can help answer questions or resolve integration issues. We’re available for:

 * Technical working sessions

 * Testing assistance

 * mTLS certification assistance

 * Sample postman collections

 * Webhook configuration assistance

 * Performance testing.

 

When testing is complete, the API Onboarding team can help move your solution to a production environment. You’ll receive the following details:
 

 * Mutual Transport Layer Security (mTLS) certificate

 * Production keys

 * Endpoints and other applicable information for your API

 We recommend testing your API solution in production prior to going live. Our API Integration team can help answer questions or resolve integration issues as you complete your production migration.
