What is the maximum Url Length the service now instance supports?

 What is the maximum Url Length the service now instance supports? and Is there a limit for sysparam_fields?

[Chris35]

Maybe sysparm_offset could be an option here.
Not sure which scope your working with here, but in the Customer Service Management API documentation, the Supported request parameters is documented.

I missed to add this point. I was using Rest API calls via POSTMAN or let say I use CURL library which is browser independent. Now what would we consider as the max length?

Error I am receiving
400 Bad Request

{"error":{"detail":"The requested query is too long to build the response pagination header URLs. Please do one of the following: shorten the sysparm_query, or query without pagination by setting the parameter 'sysparm_suppress_pagination_header' to true, or set 'sysparm_limit' with a value larger then 833753 to bypass the need for pagination.","message":"Pagination not supported"},"status":"failure"}

See this post:

The URL type field hides the Max Length field on the Dictionary form by default due to a UI Policy. Browsers support URL length up to 2,083 characters

The URL field is just a String field in terms of data type. Modifying String fields to larger Max Length is a simple process of changing the value of the Max Length field.

So all you need to do is get around the UI Policy. To do this do the following:

1. Open the Dictionary record for the URL field

2. Change the Type to "String" (don't save yet)

3. The Max Length field will appear.

4. Change the Max Length to 2,083 (or whatever you want)

5. Change the Type back to URL

6. Now you can save your changes.

How do we traverse to Dictionary record. I didn't find any option in the settings menu named dictionary ....
