So you have chosen a product and your method of integration. To run your first Smile ID job in Sandbox, please follow these step-by-step guide
Generate a Sec Key
Create a callback endpoint (for Asynchronous API use)
Write your integration code
Test your integration in the Sandbox environment
Sec Keys identify that it is your system that is making a call to our system and confirms you have authorisation to perform a job. The easiest way to calculate your Sec Key is to use one of our server side libraries, alternatively can follow the step-by-step guide in the Generate Sec Key page under the Rest API section of the docs. You'll need your API Key and Partner ID which you can get from the developer section of the portal.
If the Smile ID product you are using has an asynchronous response, you will need to setup a callback API to receive the responses. Read more on how to setup a callback in the FAQs.
In addition to getting responses via the callbacks the result of all jobs you run during your test will show up in job list in the partner portal. You can use the job list to confirm the result of your test jobs is as expected.
