# Request data from external partners

> Send a request to a data partner asking them to upload files and data for a project, then review what comes back.

Data requests let you ask a partner — a feedstock supplier, transporter, lab, or anyone outside Mangrove — to send the data you need for a project. They get a link (or an email), upload files against the specific events you asked for, and you review their submission before it lands in the project.

<Tip>
  Need the same data every week or month? See [Schedule recurring data requests](/data-collection/schedule-data-requests) instead of sending a new one-off each cycle.
</Tip>

## Send a data request

Create a request from **Data Inputs > Request Data**.

<Steps>
  <Step title="Pick recipients">
    Choose partner users in **To** (and optionally **CC**). Recipients are notified by email when the request is sent — the email is sent from your name (e.g. *From: John at Southeast Capture*).
  </Step>

  <Step title="Set the date range">
    Choose the period the partner should report on (e.g. April 1 – April 30). The partner only needs to provide data covering this window.
  </Step>

  <Step title="Select events requested">
    Under **Events requested**, pick the events you want covered — a fuel delivery, lab analysis, meter reading, etc. The partner sees these as a checklist of what to provide.
  </Step>

  <Step title="Add an optional message">
    Include a short message that appears at the top of the request page.
  </Step>

  <Step title="Send or share">
    On send, recipients get an email with a direct link. You can also copy the request URL and share it however you'd like — Slack, text, customer portal. The request shows up immediately on any apps that integrate the Mangrove API.
  </Step>
</Steps>

## Track submissions

The Request Data tab lists every outstanding request with an **N/M events** indicator — the number of requested events the partner has completed.

Open a submission by selecting the Files icon or the request URL — the submission opens in a new tab. You can edit it directly: upload or remove files on the partner's behalf, toggle which events each file covers, and add notes for your records.

## What partners see

Partners don't need a Mangrove login. They open the link and see:

* The date range you're asking about
* A checklist of events to upload files for
* Your message, if any
* An upload area

See [Submit to a data request](/data-collection/submit-to-data-request) for the partner-side experience.
