+# Add Subscriber To Kit Form Via API
+
+Because the Kit API is a bit sparse in words, I found it difficult to figure
+out exactly what I needed to do to add a subscriber via a custom form. After
+some experimenting and reading through [Course
+Builder](https://github.com/badass-courses/course-builder/blob/main/packages/core/src/providers/convertkit.ts)
+code, I was able to figure out that with the Kit v4 API there are two separate
+calls that need to be made.
+
+First, you need to create an `inactive` subscriber with the user's email (and
+first name if given) via the [Create a subscriber
+endpoint](https://developers.kit.com/v4#create-a-subscriber).
+
+```typescript
+async function createSubscriber(
+  data: SubscriberData,
+  apiKey: string,
+): Promise<Response> {
+  return fetch('https://api.convertkit.com/v4/subscribers', {
+    method: 'POST',
+    headers: {
+      'Content-Type': 'application/json',
+      'X-Kit-Api-Key': apiKey,
+    },
+    body: JSON.stringify({
+      email_address: data.email,
+      first_name: data.name,
+      state: 'inactive',
+    }),
+  })
+}
+```
+
+Since this subscriber is `inactive`, they won't show up in the Kit dashboard,
+but a subscriber record of them has been created.
+
+Second, you need to add the subscriber to something, like a form or a sequence.
+In my case, I had already created a form via the Kit dashboard, so I grab that
+_Form ID_ and stick it in my `.env`. That way I am able to [add the subscriber
+to the form by email
+address](https://developers.kit.com/v4#add-subscriber-to-form-by-email-address).
+
+```typescript
+async function addSubscriberToForm(
+  email: string,
+  apiKey: string,
+  formId: string,
+): Promise<Response> {
+  const url = `https://api.convertkit.com/v4/forms/${formId}/subscribers`
+  return fetch(url, {
+    method: 'POST',
+    headers: {
+      'Content-Type': 'application/json',
+      'X-Kit-Api-Key': apiKey,
+    },
+    body: JSON.stringify({ email_address: email }),
+  })
+}
+```
+
+This will send a confirmation email to the email address. Once the person has
+opened the email and hit 'Confirm', their corresponding `subscriber` record
+will be marked as `active` and they will be added to the list of subscribers
+for that form.
