i read another topic. they talk about zapier. but if not zapier, which provider can i use ?
To my knowledge Zapier would be the only way to integrate PayPal with ActiveCampaign.
Let me know if you have any other questions.
You can try Automate.io - its the best Zapier Alternative.
You can definitely integrate PayPal and ActiveCampaign and create automated workflows. They have plans wherein you get more actions (than zapier).
