# Add a data provider

> Register an integration that may write to sources, and store its secret.

A data provider is the identity an integration uses to write into sources. Before an integration can onboard anything, it needs a provider with access to the sources it will write to.

<Steps>
  <Step title="Open the Data providers tab">
    Open **Sources** in the left navigation and switch to the **Data providers** tab.

    Each provider shows its name, its provider ID with a copy button, the identifiers of its allowed sources, and when it was last modified.
  </Step>

  <Step title="Press New data provider">

    * **Name** — required.
    * **Allowed Sources** — the sources this provider may write to. Pick as many as needed.
  </Step>

  <Step title="Press Create">
    The dialog stays open and shows the generated secret. Copy it with the copy button.
  </Step>

  <Step title="Confirm you have copied the secret">
    <Warning>
      The secret is shown once and never again. Closing the dialog without copying it loses it for good, and the only way forward is to [reset the secret](/guides/studio/sources/reset-a-client-secret). Studio warns you once if you try, but a second attempt closes anyway.
    </Warning>
  </Step>
</Steps>

## Allowed sources

**Allowed Sources** is the whole of a provider's authorisation: it can write to those sources and nothing else. That lets you scope integrations — several providers writing to one source, or one provider restricted to a single source.

<Info>
  A source's own page lists the providers that may write to it, in the **Providers** chip row — see [Track usage of source data](/guides/studio/sources/track-usage).

With the provider ID and secret, the integration can get a token and start onboarding. See [Import data](/guides/studio/sources/import-data), or copy a working snippet from [View code examples](/guides/studio/sources/code-examples).
