How to Claim Your Instagram Account on Pinterest
Before claiming your Instagram account, you will want to make sure you are using your business account on Pinterest and that your Instagram account is open in another tab.
At the top right-hand corner, click on the arrow beside your profile picture and select Settings. From there, click on Claim on the left-hand side. Here, you will see different social media accounts you can claim. Once you see Instagram, click on the Claim button across from it.
From here, an Instagram tab will appear and ask permission to receive certain information from your Instagram account to be put on Pinterest. Information such as Profile information is required and Media is optional but you will want to select both and press Allow.
Now, your Instagram account is claimed and linked on Pinterest!
