ConvertKit + Foldr Integration
ConvertKit (now Kit) is the creator-first email platform used by authors, podcasters, and course creators. Host lead magnets on Foldr and gate them behind ConvertKit forms via the incentive-email flow.
How to Connect ConvertKit to Foldr
Create a Zap
In Zapier, start a new Zap with ConvertKit as the trigger (or action, depending on your flow).
Add Foldr as the next step
Search "Foldr" in Zapier's app picker and choose the action you want — Upload File, Create Short Link, Create Bio Page, or Submit Form.
Authenticate Foldr
Paste your Foldr API key (from foldr.space/developers) when Zapier prompts for authentication.
Map fields and turn the Zap on
Map the ConvertKit data into Foldr's input fields, test once, then enable the Zap.
Common Use Cases

ConvertKit + Foldr FAQ
How do I connect Foldr to ConvertKit?
You connect Foldr to ConvertKit via Zapier. Full steps are listed above under "How to Connect". In short: create a Foldr API key, configure the Zapier integration pointed at https://foldr.space/api/v1/, and map ConvertKit's data into Foldr's request body.
Do I need a paid Foldr plan to use ConvertKit with Foldr?
The Foldr free tier supports basic uploads via the API with 7-day expiry. For integration use with ConvertKit — higher rate limits, permanent storage, multiple API keys, and webhook subscriptions — Foldr Pro (from $5/mo) is recommended.
What Foldr features can I call from ConvertKit?
From ConvertKit you can invoke any Foldr action: uploading files (up to 2 GB each), creating short links, generating bio pages, creating hosted forms, and reading download analytics. See the Foldr API docs for the full endpoint list.
Is there an official Foldr app for ConvertKit?
Not a first-party app — Foldr integrates with ConvertKit through Zapier, which is usually a better fit because it doesn't require installing an extra app. If you'd rather have a native integration, let us know at foldr.space/contact.
