For Facebook, you can get full manage or view-only access for pages, ad accounts and product catalogs. Leadsie can also give you indirect access to Pixels and Instagram accounts through your client's ad account, or full access with our advanced sharing feature. We give you access by adding you as a partner to your client's business manager.
If your clients don't have a business manager or even an ad account, they can create it easily within Leadsie.
For Google, you can get manage or view-only access to Google Analytics, Google Ads (including Manager account / MCC support), Tag Manager, Search Console, Business Profile and Merchant Center.
For TikTok, you can get view-only and manage access to TikTok Advertising accounts.
For LinkedIn you can get access to LinkedIn company pages and ad accounts.
We also support YouTube, Shopify and Wordpress.

Leadsie is fully compliant with GDPR and CCPA. We ensure transparency, limit data processing to the minimum required, and provide clients full control over their data.
We partner with Meta, Google, TikTok (and more) and are approved for giving you access. When we grant your access to accounts, the required information (tokens) is encrypted and locked down to a database that only our Leadsie servers can access.
No one would be able to get access to your accounts or those of your clients, even if our servers were compromised. We can provide a Data processing agreement (DPA) upon request.
No, they don't need to create an account with us. Your client only needs to log in with their Facebook, Google Account, LinkedIn and/or TikTok account.. Easy peasy! 😀
Of course not! Even if you cancel your subscription with us, you will still have access to your client - unless they decide to remove your access, of course.
