To add an access key, do next:
- Go to the "Access keys" page.
- Click the "Add new" button.
- Insert the "API key" of the private application in the "API key" field.
- Insert the "Password" of the private application in the "Password" field.
- Click the "Create" button.
After checking all necessary rights, the key will be added.
For the normal operation of the API, 1 key is sufficient.
But if you plan multiple requests for data changes (more than 1 query per second), the number of keys can be increased.
