Give us access to your Meta ads

We never need your Facebook password. You add Chase Custom as a partner with our Business ID, then tick the ad account, Page and pixel we should run.

Step 4 uses this number

Our agency Business ID

When Meta asks for a partner Business ID, paste this. It is Chase Custom's Meta Business Portfolio, not a personal Facebook profile.

We'll send you this number by email or WhatsApp. If you don't have it yet, message us and we'll reply the same working day.

It looks like a long number (around 15 or 16 digits). No spaces, no letters.

  1. 1

    Open Meta Business settings

    Sign in to Facebook with the account that owns your ads, then open Business settings.

    Open Business settings
    • Go to business.facebook.com/settings.
    • If you see more than one business at the top left, pick the one that owns your ad account (usually your company name).
    • You need to be an admin of that business. If you only run the Facebook Page and not the ads account, ask whoever set the ads up.
  2. 2

    Open Partners

    This is where agencies are added. Do not add us as a person under People.

    • In the left menu, under Users, click Partners.
    • You should see a list of any agencies already connected (often empty).
  3. 3

    Choose "Give a partner access to your assets"

    There are two Add options. Pick the one that gives us access to your ad account, not the one that asks us for ours.

    • Click the blue Add button.
    • Choose Give a partner access to your assets.
    • Skip "Ask a partner to assign you their assets". That is the other way around.
  4. 4

    Paste our Business ID

    This is the box people miss. Meta asks for a partner Business ID, not an email and not a Page name.

    • Click into the Business ID field.
    • Paste our agency Business ID.
    • Click Next.
    • If Meta says the ID is invalid, check there are no extra spaces and you copied the whole number.
  5. 5

    Assign your ad account

    Give us permission to run campaigns. Leave billing and ownership with you.

    • Open the Ad accounts tab.
    • Turn on the ad account we should use (the one that pays for your Facebook and Instagram ads).
    • Set permission to Manage campaigns (sometimes labelled Partial access for ads). That lets us create, edit and pause ads.
    • You do not need to give Full control unless we specifically ask.
  6. 6

    Assign your Page, Instagram and pixel

    Ads cannot run without the Page and tracking pixel attached to the same business.

    Facebook Page

    Create ads / manage content. We need this to run ads from your Page, not a personal profile.

    Instagram

    Advertise. Only if your Instagram is linked to the Page.

    Pixel / Dataset

    View and manage (or Full control on the dataset). This is how Meta learns which leads become jobs.

    • Click Assign assets (or Next) after the ad account.
    • Tick the matching Page, Instagram account and pixel / dataset.
    • Click Save or Assign assets to finish. You should then see Chase Custom in your Partners list.
  7. 7

    Tell us you're done

    Access is instant on Meta's side. We still need a nudge so we can check it and start the campaign.

Don't have Business settings yet?

If the link above asks you to create a business, you probably only have a personal Facebook Page. Create a free Business Portfolio first (Meta walks you through it), claim your Page and ad account, then come back to step 1. Official help: Give a partner access to your assets.

  • Never send us your Facebook password.
  • Don't add a Chase Custom staff member under People. Partners is the right place.
  • You can remove us any time from the same Partners screen.
