ACC Issues API: Maximum Length Changes

Attention Autodesk Construction Cloud (ACC) Issues API developers!
Autodesk is planning to change the maximum character limit allowed for the following three fields in ACC issue items through API: title, description, and locationDetails. This change will make the consistent maximum character limits applied to API and the web user interface (UI).
The table below lists the current and new maximum characters allowed in API.
Field | Maximum Characters | |
Current | New | |
title | 4200 | 100 |
description | 10000 | 1000 |
locationDetails | 8300 | 250 |
The foregoing changes apply to the following two endpoints for ACC Issues API:
Note: The foregoing changes do not apply to those fields in the following read endpoints for ACC Issues API to allow access legacy data. i.e.,
Background
These new maximum character limits have been applied to the web user UI. However, the API allows for greater maximum characters, causing the discrepancy in the user experience (e.g., the user can create a long title using the API, but will not be able to see the full title in the web UI. This change only affects the ACC Issues API. BIM 360 Issues API remains unchanged.
Action Required
If you are using ACC Issues API to create/update issue items, please ensure that the number of characters for the fields identified above does not exceed the new maximum character limits. If your code is written for the greater maximum character limits, you must update your application to reduce the maximum character limits for the identified fields by May 15, 2025, after which date you will no longer update those fields with values that are longer than the new maximum character limits.
Additional Information
Below is a list of answers to a few anticipated questions about this change:
Q1: What will happen to the existing data that is longer than the new limit? Will the date be truncated?
A1: Any existing data will not be changed. The data remains as is.
Q2: What will happen if I patch or modify an attribute by API which has long characters with old limit?
A2: You will be able to edit it only to a new title which will be compatible with the new limit.
Q3: In our workflow, the attribute with old limit is still needed, what is the suggestion?
A3: If you need a string longer than the new limit, you could consider storing the string to the custom attribute of issue (currently, 2500 chars for paragraph type), or create issue comments (currently, 100000 chars are accepted). You could also store the long string to text file and attach the file as reference or attachment.
Q4: I have an issue with a long title/description/locationDetails, and I want to edit another attribute, for example, assignee. Will I be able to do so without changing those fields with long chars?
A4: Yes, we only enforce title/description/locationDetails. No impacting with other attributes.
