Product surfaces

The integration is more than a logo connection

Plandalf sits between the sales surface, the payment processor, and the tools that run the work after purchase. These are real product screens for the records a seller or builder should inspect before sending traffic into Offers, Automations, and connected integrations.

The Numi integrations settings page showing Stripe, PayPal, TaxJar, and Avalara connection options.

Connect the payment and tax layer

Use the integrations surface to confirm Stripe, PayPal, TaxJar, Avalara, and test-mode routing before a buyer reaches checkout.

The Numi offer editor with layout, products, automation, invoices, and settings controls.
The Numi offer editor automation tab showing sequence controls beside the checkout canvas.

Route purchase events after checkout

Automations and sequences move purchase context into fulfilment, email, CRM, webhooks, support, reporting, and lifecycle follow-up.

The Numi Stripe payment methods settings page showing cards, wallets, bank transfers, and buy now pay later options.

Choose checkout payment methods

Payment options decide which cards, wallets, bank transfers, and pay-later methods appear before a buyer submits checkout.

The Numi offer invoices records view showing customer invoice rows and payment status.

Preserve invoice and support records

Invoice records keep customer, product, line item, payment state, refund, tax, and support context attached to the sale.

The Numi checkout element palette showing content, interaction, and selling blocks.

Build the checkout surface sellers edit

Checkout templates, buy buttons, custom styles, order bumps, upsells, and coupons keep seller-owned controls out of integration code.

The Numi Developer API documentation with sidebar navigation and SDK method reference.

Hand off to API and SDK docs

API keys, SDK checkout, webhook docs, and event references are the implementation handoff once the integration pattern is chosen.

Builder paths

Choose the job the integration needs to do

Use the browser above when you know the tools. Use these paths when you know the workflow: checkout, payment, fulfilment, lifecycle, tax, affiliate attribution, or records. Each path links into the relevant features, platforms, and stack guides.

The Numi editor top bar showing preview and share controls for a buying surface.

Sell from a website or newsletter

Start with the audience surface, then open a hosted checkout, embedded offer, modal checkout, or buy button that carries the offer context.

The Numi Stripe payment methods settings page showing cards, wallets, bank transfers, and buy now pay later options.

Connect the processor without becoming the processor

Keep Stripe or PayPal as the account that charges the buyer while Plandalf owns the offer, invoice, payment state, and follow-up context.

The Numi offer editor automation tab showing sequence controls beside the checkout canvas.

Send fulfilment and lifecycle work downstream

Use purchase events, automations, and webhooks to update access, start email sequences, sync CRM records, and notify support or finance tools.

The Numi automation integrations screen showing connected workflow destinations.

Handle tax, affiliate, and records work

Keep tax calculation, affiliate attribution, invoice records, line items, and support context attached to the same checkout event.

API

Not on the list? Wire it up in an afternoon.

Every checkout event can fire a webhook. API-driven workflows can connect products, prices, invoices, and fulfilment records. Most missing integrations are a Zapier hop or a 30-line Cloudflare Worker away.
