1. Using Vtiger API

If you prefer a safer method, you can use Vtiger’s API to delete custom fields and blocks. Here’s how you can do it using the API:

Delete a Custom Field

1. Obtain API Access:
   Ensure you have access to Vtiger’s API and obtain an API key or authentication token.
2. Create a Request to Delete the Field:
   Use a REST API client or code to send a request to Vtiger’s API. For example, you might use cURL or a programming language like Python. Example using cURL:

   curl -X POST "https://your-vtiger-url/webservice.php" \
   -d "operation=delete" \
   -d "sessionName=YOUR_SESSION_ID" \
   -d "elementType=Field" \
   -d "elementID=FIELD_ID"

Replace:

• YOUR_SESSION_ID with your active session ID.
• FIELD_ID with the ID of the field you want to delete.

3. Check API Documentation:
Refer to the Vtiger API documentation for specific details about deleting custom fields or blocks, as the exact parameters and methods can vary.

   Run the following SQL commands to delete the custom field. Replace fieldid with the actual ID of the field.

   -- Delete the field from the field table
   DELETE FROM vtiger_field WHERE fieldid = 'FIELD_ID';

   -- Optionally, clean up related entries
   DELETE FROM vtiger_fieldmodulerel WHERE fieldid = 'FIELD_ID';

4. Clear Cache and Rebuild Indexes:
   Clear any caches and rebuild indexes if necessary to ensure the system reflects the changes.

Delete a Custom Block

   -- Optionally, clean up related entries
   DELETE FROM vtiger_field WHERE blockid = 'BLOCK_ID';

4. Clear Cache and Rebuild Indexes:

3. Additional Considerations

• Testing: Always test changes in a staging environment before applying them to production.
