# GRP AP Invoice

The GRP AP Invoice source connects to the Dubai GRP accounts payable SOAP service and loads invoice, payment, vendor, and project queries into Less.

Write operations from the interface specification, such as insert, update, and delete, are not called.

<Steps>
  <Step title="Credentials">
    Enter the gateway **API key** and the **GRP username** sent in each request. The **service URL** defaults to the staging endpoint. Replace it with the production URL when Dubai Digital provides one.
  </Step>

  <Step title="Date Interval">
    Choose the start and end dates. Payments, payment status, vendors, and the DHA and DMI extracts use this range. Dates are sent as `YYYY-MM-DD`.
  </Step>

  <Step title="Tables">
    Select the queries to extract. Each selected query is stored as its own table.
  </Step>

  <Step title="Filters">
    Only the filters for the queries you selected are shown, grouped by query. Fill in the required inputs. AP payments, invoice interface status, and vendors only use the date range, so this step stays empty when those are the only queries selected.
  </Step>
</Steps>

Contact your GRP administrator if you do not have a gateway API key or service username.
