Connect a payment gateway once and every new invoice carries a pay button, so clients can pay you the moment they open it. **In this guide you'll learn how to:** - Connect a payment gateway to OneSuite - Enter the keys each gateway needs - Check which gateways your invoices can use - Turn online payment on or off for one invoice ## Before you start - Open an account with the payment gateway you want to use, and find its API keys. They are usually in the gateway's developer or API settings. - You need access to your business's admin settings. If you can't see **Integrations** in **Settings**, ask an admin. ## How to connect a payment gateway You connect gateways in **Settings**, **Integrations**, **Payment**, on the **Payment Methods** page. 1. Click your name at the bottom of the sidebar, then click **Settings**. 2. Under **Integrations**, click **Payment**. 3. On the **Payment Methods** page, click the card for your gateway. A gateway you haven't set up yet shows **Connect**. 4. In the dialog that opens, paste the keys from your gateway account. The table below lists what each one asks for. 5. Click **Save**. The card now shows **Connected**. OneSuite rejects an empty field, for example **Please, provide your Stripe API key**. To replace your keys later, click the card again, enter the new keys and click **Save**. | Gateway | What OneSuite asks for | | --- | --- | | Stripe | **Stripe Secret/API Key** | | PayPal | **PayPal API Key**, **PayPal API Secret** | | Quickpay | **Quickpay API Key**, **Quickpay Private Key** | | Razorpay | **Razorpay API Key**, **Razorpay API Secret**, **Razorpay Webhook Secret** | | HitPay | **HitPay API Key**, **HitPay Salt** | | CHIP | **Brand ID**, **Secret Key** | For Razorpay, the dialog also shows a webhook URL. Add that URL in your Razorpay Dashboard and subscribe it to the `payment_link.paid` event. ![Settings, Integrations, Payment page showing the Payment Methods cards with Stripe marked Connected](https://help.onesuite.io/wp-content/uploads/2026/10/adding-your-payment-methods-1.webp) ## How to check which gateways your invoices can use You can see every gateway's status in **Invoices**, **Configure**, **Getting paid**, under **Online payments**. 1. Click **Invoices** in the sidebar. 2. Click the **Configure** tab, then **Getting paid**. 3. Under **Online payments**, check that your gateway shows **Connected**. This list is read-only. To connect or change a gateway, click **Manage in Settings › Integrations › Payment**. A gateway you connect is switched on for new invoices. An invoice created earlier keeps its own choice, so switch the gateway on in that invoice's **Payments** panel, save it and send it again. ## How to turn online payment on or off for one invoice You control online payment per invoice with the **Online payments** switch in the invoice editor's rail. 1. Open the invoice in the editor. 2. In the rail, open **Payments**. 3. Switch **Online payments** on to put a pay link on the invoice for the gateways listed below it. 4. Under **Gateways**, switch each connected gateway on or off for this invoice. 5. Save the invoice. If a gateway isn't connected yet, the panel names it with a **Connect in settings** link. Your client sees a **Pay Now** button for each gateway you leave on, under **Online Payment Methods** on the web invoice. There is no disconnect button on the **Payment Methods** page. To stop offering a gateway on an invoice, switch it off in that invoice's **Payments** panel. Not using OneSuite yet? Start your free trial → ## FAQs ### Which payment gateways does OneSuite support? OneSuite supports Stripe, PayPal, Quickpay, Razorpay, HitPay and CHIP. You connect each one in **Settings**, **Integrations**, **Payment** with the API keys from your gateway account. ### Why doesn't my old invoice show a pay button after I connected Stripe?

Connect each gateway on the **Payment Methods** page. On each invoice, switch on the gateways you want under **Payments**, **Gateways**, and your client chooses how to pay. ### How do I disconnect a payment gateway? The **Payment Methods** page has no disconnect button. To stop a gateway appearing on an invoice, switch it off in that invoice's **Payments** panel in the editor. ### Can I just take bank transfers instead? Yes. You can print your bank details on invoices with or without an online gateway.
