Engineering Director hosts a REST API for fetching data related to raster maps, vector maps, and data structures we process. The API is a standard OAuth-style JSON API for fetching and retrieving data.

You should get an API token from support@engineeringdirector.com via email. When interacting with our API, include that token in a standard Authorization: Bearer header. For example: the below curl example should work

Error messages will be in a standard format and will come with specific HTTP error codes. For example:

For details on status/error codes, please see documentation on HTTP status codes.

The EDI API should accept most headers but will ignore unnecessary ones. It is not necessary to include a Content-Type or Accept header. The API will return a Content-Type: application/json regardless of the Accept or Content-Type header requests.

We have a simple endpoint which if you send a GET request to (/partner/test) it will return an HTTP 200 with a JSON payload with timestamp information.

We don't run an API sandbox. If you need a separate API key for integration tests or other implementation testing, please contact our support.

We have several APIs, each documented on their own page in our knowledge base. Please work from the list below.
