How do I correctly format parameters to create a GLPI ticket via API?

When constructing your JSON body, make sure that you use proper JSON syntax (i.e., standard quotes) and that you nest your parameters under an "input" object. For example, your request should look like this:

BASHCopied
curl -X POST \
  -H "Content-Type: application/json" \
  -H "Session-Token: xxxxxxxx" \
  -d '{
        "input": {
          "name": "Ticket Title",
          "content": "Ticket Description",
          "itilcategories_id": 123,
          "type": 2,
          "locations_id": 45
        }
      }' \
  "http://xxx/apirest.php/Ticket/"

Key points:

• Proper Quotes: Use standard double quotes (") for both your JSON keys and values. Some of the examples in the documentation may use non-standard quotes which lead to formatting issues.

• Nested Input Object: All parameters (name, content, itilcategories_id, type, locations_id) must be nested inside the "input" object as shown.

• Endpoint URL: Ensure you have the correct endpoint (http://xxx/apirest.php/Ticket/).

Once you obtain a valid session token using the initSession call, include that token in the "Session-Token" header and the request should work as expected.

If you continue to receive errors, verify that:

• The session token is valid.
• The values for category, type, or location IDs are correct.
• There are no hidden formatting characters (sometimes copied quotes from rich text sources can cause issues).

This should resolve the parameter formatting error you're encountering with GLPI's API.
