Connect PayPal to WhatsApp, Instagram, TikTok and AI Chat

By Alva Chew 6 min read Updated November 7, 2026

Customers message you on WhatsApp, Instagram, Messenger, TikTok, Telegram, web chat or email, and many of them want to pay with PayPal. AeroChat creates the PayPal invoice for the amount agreed in the conversation, sends the payment link in the same chat, and answers “did my payment go through” from the invoice in PayPal. It connects through PayPal’s public API. Airwallex payment links are built into AeroChat, and PayPal is there for businesses that already use it. You describe the workflow in your own words, and AeroChat builds it.

What you can do with PayPal and AeroChat

  • Send a PayPal invoice from the chat. When a customer confirms an order, a quote or a booking, AeroChat creates the invoice with the items and amount and sends the link to pay.
  • Answer “did my payment go through?”. AeroChat checks the invoice in PayPal and tells the customer whether it is paid, partly paid or still open.
  • Take a deposit before you confirm. AeroChat sends an invoice for the deposit and confirms the booking once PayPal shows it as paid.
  • Find a customer’s past invoices. AeroChat searches PayPal by the customer’s email and tells them what is open and what is paid.
  • Resend or replace a link. If an invoice was missed or the amount changed, AeroChat sends a reminder for the open invoice or creates a corrected one.
  • Pass refund requests to your team. AeroChat collects the invoice number and the reason and hands the conversation over.

Works on every chat channel

Your customers message you wherever they already are. The same PayPal connection and the same workflows run on every channel AeroChat supports, and PayPal stays the record whichever one they use.

Channel What your customers can do
WhatsApp Message your WhatsApp Business number to get a PayPal invoice for an order or a booking, or ask whether a payment went through. Voice notes are transcribed, so a spoken request works too.
Instagram Send the same requests by direct message. A comment on your post can get an automatic reply that moves the conversation to a DM.
Facebook Messenger Send the same requests to your Facebook Page. Comments on your Page posts can get an automatic reply too.
TikTok Send the same requests by TikTok direct message or TikTok Shop buyer chat. Both arrive in the same TikTok inbox.
Telegram Send the same requests to your business on Telegram.
Web chat Do the same from the chat on your website, without leaving the page.
Email Write to your Gmail or Office 365 address and get the same answer the chat gives.

How the connection works

AeroChat connects through PayPal’s public REST API. It creates, sends and reads invoices through the Invoicing API, and it can create an order with a PayPal checkout link through the Orders API. It reads the invoice status, such as sent, paid or partly paid, so it knows when the customer has paid. Each workflow uses only what its recipe asks for.

To connect, log in to the PayPal Developer Dashboard with your PayPal business account, open Apps and Credentials, create a REST app for AeroChat in Live mode, and copy its client ID and secret. Paste both into the AeroChat dashboard when AeroChat asks. You can test the whole flow first with a Sandbox app.

You describe the workflow in your own words. AeroChat builds it as a draft, works out which PayPal calls it needs, and asks you to connect. Keys and credentials are entered in the AeroChat dashboard and never pass through the conversation.

Workflows to copy

Copy this into AeroChat

When a customer confirms what they want to order, create a PayPal invoice addressed to their email with each item, the quantity and the price, and a due date of 3 days from today (example). Send it, then share the payment link in the chat with the invoice number and total. When PayPal shows the invoice as paid, confirm the order and tell them what happens next.

Copy this into AeroChat

When a customer asks whether their payment went through, find the invoice we sent them in this conversation. If there is none, ask for the invoice number or the email they used and search PayPal for it. Tell them whether it is paid, partly paid or still open, with the amount and date. If it is still open, send the payment link again. If they ask for a refund, hand the conversation to a team member.

Change the amounts and rules to your own before you paste them.

Who uses it

These industry recipes take payment by link. The same steps work with PayPal for businesses that already use it:

What stays in PayPal

PayPal stays your record of every invoice and payment. Customers pay on PayPal’s own page, so their card and PayPal login go to PayPal and never to AeroChat. AeroChat does not process or hold any money. Payouts, disputes, refunds and reports stay in your PayPal account.

AeroChat handles the conversation. It creates and reads the invoices your recipe asks for and leaves the rest to PayPal and your team.

Questions

Does AeroChat work with PayPal?

Yes. AeroChat connects through PayPal’s public API with the client ID and secret of a REST app you create in your PayPal Developer Dashboard.

Can customers pay with PayPal through WhatsApp?

Yes. AeroChat creates the PayPal invoice and sends the link in the WhatsApp chat. The customer taps it, pays on PayPal’s page, and AeroChat can confirm the payment from the invoice status.

Do I need a developer?

No. You describe the workflow in your own words, create a REST app in PayPal and paste in its credentials, and switch it on. AeroChat builds the PayPal connection from your description and shows a checklist of what is left to do.

Which plan do I need?

Workflows via Skills are on every plan. Choose by message volume: Starter covers 500 AI responses a month and 3 seats, Growth covers 2,000 responses and 10 seats and adds payment links and broadcasts, and Advanced covers 5,000 responses and 25 seats.

Using a different system? If it has a public API, it connects to AeroChat the same way: describe what you want, paste in its key, and it runs.
