Integrations

​

What this page is for

The Integrations page is where you connect your White Label app to the services that make day-to-day operations possible:

• Payments & subscriptions (so you can charge customers)
• Voice and SMS (so calling and messaging features work)
• Email sending (so customers receive important emails)
• Live chat (so customers can contact your team in real time)
• Marketing tracking (so you can measure acquisition and conversions)

Open it here: Open Integrations

Screenshot: the Integrations overview. Each card opens a setup panel with the exact fields you must fill in.

Important: Card badges like Connected or Required reflect your current setup and can vary depending on your account and plan.

​

Before you connect anything

A few habits make integrations smoother (and safer):

• Use the right admin account in each provider (Stripe, Twilio, etc.) so you can access keys and settings.
• Store keys securely (treat them like passwords).
• Limit access to people who need it. Don’t paste keys into shared docs or chats.

Tip: If an integration doesn’t work immediately, double-check for extra spaces at the beginning/end of a key before trying anything else.

​

How connecting an integration works

Most integrations follow the same pattern:

1. Click an integration card (for example Twilio or SendGrid).
2. A side panel opens with required fields (marked with *).
3. Copy the values from the provider dashboard.
4. Paste them into Callin and click Save.

​

Stripe

What it’s for: Stripe is used for payment processing. This is the integration that typically enables you to run a real subscription business: accepting payments, charging customers, and managing subscriptions. When you need it: If you plan to create paid plans and charge customers (monthly, yearly, etc.), Stripe is one of the first integrations to set up.

​

What you’ll need (as shown in the panel)

• Secret Key*
• Webhook Secret*
• Webhook Secret Connect*
• Client ID*

Screenshot: Stripe setup requires four values and is saved with the Save button.

​

How to connect Stripe

1. Open the Stripe card.
2. In your Stripe dashboard, copy the required values.
3. Paste each value into the matching field in Callin.
4. Click Save.

Important: If you rotate keys or change webhook settings in Stripe later, you must come back here and update the values.

​

Twilio

What it’s for: Twilio powers voice calls and SMS. It’s the integration that makes calling and messaging features possible and also supports phone number management. When you need it: If your White Label includes inbound/outbound calls or SMS, Twilio will usually be essential—and may appear as Required.

​

What you’ll need (as shown in the panel)

• Account SID*
• Auth Token*

Screenshot: Twilio setup requires an Account SID and Auth Token.

​

How to connect Twilio

1. Open the Twilio card.
2. From your Twilio dashboard, copy your Account SID and Auth Token.
3. Paste them into the corresponding fields in Callin.
4. Click Save.

Tip: If calling/SMS doesn’t work later, Twilio is the first integration to re-check.

​

SendGrid

What it’s for: SendGrid is used to send emails from your White Label app—especially automated and notification emails customers rely on (for example: confirmations and system messages). When you need it: If your customers should receive emails from your branded experience, set up SendGrid early.

​

What you’ll need (as shown in the panel)

• API Key*
• Sender Email* (a verified sender email)

Screenshot: SendGrid setup requires an API Key and a Sender Email.

​

How to connect SendGrid

1. Open the SendGrid card.
2. Copy your API Key from SendGrid.
3. Enter a Sender Email that is verified in SendGrid.
4. Click Save.

Common mistake: Using a sender email that isn’t verified in SendGrid. If emails don’t send, verify the sender first.

​

Intercom

What it’s for: Intercom enables live chat and customer support inside your app. It’s a common option when you want customers to message your team without leaving the product. When you need it: If support and onboarding are part of what you sell, Intercom can make your White Label feel more “product-ready.”

​

What you’ll need (as shown in the panel)

• App ID* (from Intercom workspace settings)

Screenshot: Intercom setup requires an App ID.

​

How to connect Intercom

1. Open the Intercom card.
2. Find your App ID in your Intercom workspace settings.
3. Paste it into Callin and click Save.

Tip: Use the Intercom workspace that matches your support team. That way, customer messages go to the right place.

​

Brevo Chat

What it’s for: Brevo Chat enables a chat widget for real-time customer conversations. The panel references Brevo (formerly Sendinblue), and the goal is to activate chat using a widget key. When you need it: If you prefer a lightweight chat widget experience (instead of Intercom), Brevo Chat is an option.

​

What you’ll need (as shown in the panel)

• Chat Widget Key* (also described as a Chat Widget Key/API Key)

Screenshot: Brevo Chat setup requires a Chat Widget Key.

​

How to connect Brevo Chat

1. Open the Brevo Chat card.
2. In your Brevo dashboard, copy your Chat Widget Key (or Chat Widget Key/API Key).
3. Paste it into Callin and click Save.

Important: Keep the widget key private. Anyone with access could potentially use it in another environment.

​

Analytics & Tracking API Keys

What it’s for: This integration connects your White Label to marketing and analytics tracking. Based on the setup instructions shown in the panel, it supports:

• Google Ads tracking via a Pixel ID
• Google Analytics (GA4) tracking via a Measurement ID

Why this matters for White Label: If you run paid campaigns or want clean attribution, you want conversions and traffic tracked for your brand so you can measure performance and ROI.

​

What you’ll need (as shown in the panel)

• Google Ads Pixel ID (example format: AW-123456789)
• Google Analytics Measurement ID (GA4) (example format: G-XXXXXXXXXX)

Screenshot: tracking setup where you paste your Google Ads and GA4 IDs and then save.

​

How to connect tracking

1. Open Analytics & Tracking API Keys.
2. In Google Ads, copy your Google Ads Pixel ID and paste it into the matching field.
3. In Google Analytics (GA4), copy your Measurement ID and paste it into the GA4 field.
4. Click Save.

​

What happens after you save (as described in the panel)

• Tracking scripts can be injected using the IDs you entered (for this brand).
• If a field is left empty, that provider’s script should not load for this brand.
• Access to view/change these IDs is limited to users with the right level of access (as noted in the panel).

Tip: Keep a simple checklist for every new brand you launch: connect tracking early so you don’t lose attribution data during your first campaigns.
