Click Settings in the TravelTime toolbar to open the add-in configuration. Changes are saved when you click OK.
Enter your App ID and API key. If you don't have them yet, click Get a free API key - see API access.
The Endpoint is the TravelTime API address. Leave the default unless TravelTime has given you a different one; reset restores it.
On by default. When ticked, a search in the toolbox tools that the API rejects (for example a location in the sea) is noted in the tool's messages and skipped. The tool carries on, writes every successful result, and ends with a warning listing the searches that are missing from the output. When unticked, the first failed search fails the whole run.
Isochrone tools with Result Aggregation set to INTERSECTION, and all Location Analytics tools, always fail the run on a failed search, because a missing location would make their answer wrong rather than smaller.
Off by default. When ticked, the toolbox tools count the searches they send and pause for 60 seconds before going over the limit. Set it to the hits-per-minute limit of your plan to avoid 429 errors.
A hit is one search: one isochrone, one H3 search, one Travel Time Matrix origin or one route. Geocoding requests are not counted. The count starts again from zero for each tool run, so back-to-back runs can still go over your limit.
