Update existing Tallyfy tasks via PUT API endpoints for both process tasks and one-off tasks - modify title deadline assignees and form field values through taskdata objects with field-type-specific formatting for text dropdowns radio buttons and checkboxes.
Update process
PUT /organizations/{org_id}/runs/{run_id}
Updates properties of an existing process (run). You only need to send the fields you want to change.
Replace {org_id} with your Organization ID and {run_id} with the process run ID.
Authorization: Bearer {your_access_token}Accept: application/jsonX-Tallyfy-Client: APIClientContent-Type: application/json
Send a JSON object with only the fields you want to modify. Updatable fields:
name(string): Process name (max 550 characters).summary(string): Process description text.owner_id(string): User ID of the new process owner. Must belong to the organization.starred(boolean): Whether the process is starred/favorited.is_public(boolean): Whether the process is publicly accessible.publicly_hidden_fields(array): Field IDs to hide from public view.users(array of strings): User IDs assigned to the process. Replaces all current user assignees.groups(array of strings): Group IDs assigned to the process. Replaces all current group assignees.prerun(object): Update kick-off form field values. Keys are field timeline IDs, values depend on field type. See Launch process.

Edit Processes > Edit tasks and process properties
Edit running process properties in Tallyfy - change the process name, owner, and notes directly from the Settings panel without restarting the workflow.
Update an existing template’s properties by sending a PUT request with the required title field and any optional fields you want to change - noting that user or group arrays replace the entire existing list rather than appending to it.
Code Samples > Managing processes (Runs)
Use the Tallyfy API to launch, list, update, archive, restore, and permanently delete processes (runs) - the live instances created from your templates.
