Lemrock runs your ChatGPT Ads campaigns from an OpenAI advertiser account in your company’s name. Create the account → invite Lemrock as Admin → Lemrock sets up the account, syncs your catalog and launches the campaigns. If your company already has an OpenAI advertiser account, see If you already have an advertiser account first.

​
1. Create your advertiser account

  1. Go to ads.openai.com, click Start now, and sign in with your OpenAI account, or create one.
  2. When asked for your website URL, choose to skip and go straight to Ads Manager. Lemrock builds the campaigns.
  3. Enter your company’s details: legal name, website, country or region, currency and time zone.
When Ads Manager asks you to finish account setup (billing and logo), click Complete later. Lemrock does both.

​
2. Invite Lemrock as Admin

  1. In Ads Manager, go to Settings → Users → Invite.
  2. Enter the email address your Lemrock contact gave you.
  3. Change Role to Admin. It’s set to Member by default, which isn’t enough to set up billing.
  4. Tell your Lemrock contact the invite is sent.
If your company requires single sign-on (SSO) for OpenAI Ads, make sure your Lemrock contact can still sign in with their own email.

​
3. Lemrock finishes the account setup

Don’t add your own payment method to this account. Lemrock adds its own, and uploads your logo, which appears next to your ads. Campaigns can’t run until billing and the logo are set up.

​
4. Lemrock syncs your catalog

Lemrock connects to your product feed and syncs it with your OpenAI account. You don’t send anything to OpenAI: just keep your feed up to date.

​
5. Lemrock launches your campaigns

Lemrock creates and manages the campaigns, ad groups, ads and budgets. Your Lemrock contact tells you if they need anything else before launch.

​
If you already have an advertiser account

You haven’t set up billing on it: use it. Skip to step 2. You already run your own campaigns on it with your own card: keep it as is and create a second advertiser account for Lemrock:
  1. In Ads Manager, click your account name at the bottom left.
  2. Click your account name again, then Create account.
  3. Follow step 1 for the new account, then step 2.
Your campaigns bought directly from OpenAI stay on your existing account and your card. Your campaigns bought through Lemrock run on the new account. If Create account is missing, tell your Lemrock contact and we’ll find the next step with you.
