Let’s get your API call returning all the data you need! The problem with your current URLs is that you’re not formatting request parameters correctly to match Bitrix24’s REST API rules. Here’s how to fix it:

Key Bitrix24 REST Parameter Rules #

List-based APIs like bizproc.task.list rely on array-style parameters to specify which fields to return, filters, and sorting. For example, to include specific fields in your response, you need to use the select[]=FieldName syntax instead of just listing the field name.

Correct URL Example #

Suppose you want to fetch task ID, name, activity details, and status. Your properly formatted URL would look like this:

https://b24-6dil6a.bitrix24.com/rest/bizproc.task.list.json?auth=ce782c610056ed050056ed0100000001282303d5d786cc952d4b7e2bf51a6f12fe4bfd&select[]=ID&select[]=NAME&select[]=ACTIVITY&select[]=STATUS

Parameter Breakdown #

• select[]=FieldName: Repeat this for every field you want in the response. Refer to the official docs you linked for the full list of available fields.
• filter[FieldName]=Value: Add this if you need to filter results (e.g., filter[STATUS]=1 to only fetch active tasks).
• order[FieldName]=ASC/DESC: Use this to sort results (e.g., order[ID]=DESC to get the newest tasks first).

Why Your Previous URLs Failed #

• Your second URL used ACTIVITY as a standalone parameter without assigning a value or using the required select[] format. Bitrix24 doesn’t recognize this as a valid request to include the field.
• Always pair parameter names with their values, and use the [] array syntax for parameters that accept multiple inputs (like select).

Quick Debugging Tips #

• Stick with .json instead of .xml—it’s far easier to read and debug responses.
• Start with a small set of fields (e.g., ID and NAME) to confirm the call works, then add more fields one by one.
• Double-check parameter names against the docs—Bitrix24 fields are case-sensitive!
