If you only see zero API calls for your integration key in the production Usage Center, it most likely means all your testing took place in the demo sandbox environment, and no calls have actually been made in production.

​@JohnSantos thanks for your response.

I am seeing this for my integration key in the demo sandbox API Usage Center. I want to submit the integration key for App Review but it isn’s allowing me because it requires 20 successful API calls to start this process.

Check the base URL (API endpoint) you are using in your code. For the developer environment, it should typically be one of:

https://demo.docusign.net/restapi
https://account-d.docusign.com (if your account is on the newer demo domain)

Hello ​@cjDev,

As John Mentioned, there are some cases where an API call is not exhibited in the API Usage Center, it may happen for some of the following cases:

• Some API Methods such as createRecipientView
• Some API errors.(You can use the logging tool or DocuSign Monitor to track these).
• Some Third Party Integrations may not appear in the API usage Center.

Note that these are some examples, and it should not be limited by only these causes. Are you trying to promote an integration, can you confirm which API methods are you using? Note that some API Methods may not count to the 20 successful required API calls for a Go-Live Request.

Also, simply authenticating with the API or retrieving user information is not enough to meet the 20-call requirement. You must send envelopes, sign them, or perform the actual workflow that your application will use in production.
