API Implementation Essentials
We work with a REST API that uses GET and POST methods. All data is read in JSON, and our responses are also in JSON.
Null Strings: Our API does not accept strings defined as null. If a field is defined as a string, do not send it as null. If you want the field to be empty, send it as an empty string ("") or simply omit it from your request.
Booleans vs. Strings: true and false (booleans) are not equivalent to "true" and "false" (strings). Be sure to use the correct type to avoid test failures.
Time Management
UTC+0 Time Zone: Our server stores dates and times in the UTC+0 time zone. Most frameworks and browsers automatically perform this conversion when dealing with datetime objects.
