I started using a program called Post Planner (https://www.postplanner.com/) to schedule other social media platforms and I'd like to use it for Pinterest too. I looked them up on the official Pinterest partners list here: https://business.pinterest.com/en/pinterest-partners/
Post Planner is not on this list. I asked Post Planner and they say they are an approved partner and were approved to use Pinterest's API. I don't want to use a program for Pinterest that is not approved and put my account in jeopardy. How do I know if they are an approved partner and if I can use their program for Pinterest?
