Before you start

  • Log in details for your Instantly account.
  • OneTimeSecret open in another tab. You will use it to send the key. How it works.

Note

Instantly has two API versions. The old one (V1) was switched off in January 2026. Old V1 keys do not work with V2. Please create a new key with the steps below, even if you already have an old one.

Get your API key

  1. Log in to Instantly

    Go to app.instantly.ai and log in.

  2. Open Integrations

    Go to app.instantly.ai/app/settings/integrations. This is the Integrations page in your settings.

  3. Open API Keys

    Click API Keys in the left sidebar.

  4. Create a new key

    Click Create API Key.

  5. Name the key

    Type a name, for example "Uplifted Consulting". The name is only a label for you.

  6. Choose the scopes

    Scopes decide what the key is allowed to do. Choose all:all. This gives full access, so we can work on campaigns, leads, and accounts without asking you for a new key later.

    Tip

    If you prefer to limit access, tell us first. We will tell you exactly which scopes to tick. Scopes cannot be changed later, so a wrong choice means making a new key.

  7. Create and copy the key

    Click Create. Then copy the key straight away.

    Careful

    Instantly shows the key only once. If you close the window before copying it, you will need to make a new key.

Send it to us

Send it with OneTimeSecret

Paste the key into OneTimeSecret, create the link, and send us only the link. Label it "Instantly API key".

Something not right?

I don't see API Keys in Integrations

You are probably logged in as a team member without admin rights. Ask the workspace owner to do these steps, or to give you admin access.

I closed the window before copying the key

That is fine. Create another key with the same steps. You can delete the one you did not copy.

Will a new key break anything?

No. Instantly lets you have several keys at once. Making a new key does not stop your existing keys or tools from working. Just do not delete keys that other tools use.
