Payments
Serahin handles pre-order payments, while Manifly offers monthly memberships. Both use a shared payment service so the product applications do not store sensitive payment details or integrate directly with provider APIs.
Serahin
A customer opens a seller's campaign on Serahin and reviews the product, the quota, and the price.
Checkout shows manual payment and, when enabled for that campaign, automatic payment with the available method, amount, and fees.
For automatic payment, the customer continues to the provider's hosted page. Returning to Serahin alone does not mark the transaction as paid.
Status changes after a manual payment is verified or the payment service reports authoritative PAID status. The buyer can then follow progress through the order portal.
Manifly
The user selects Free, Lite, Plus, or Pro. Each plan sets WhatsApp capacity and limits for accounts, budgets, categories and the AI assistant.
Manifly shows the plan, add-ons, monthly amount, auto-renewal, and billing date before checkout.
When production checkout is enabled, the payment service creates a Xendit subscription checkout and the user pays on the provider's hosted page.
Membership activates only after authoritative payment status is received. Visiting the success URL cannot activate a plan by itself.
A Serahin payment relates to an order in a seller's campaign; the seller and campaign terms govern production, delivery, and resolution. A Manifly payment is a software membership fee paid to Sadatech. The applicable details are shown before confirmation.
Automatic checkout is processed on a provider-hosted page through Sadatech's payment service. Sadatech products do not ask for or store full card numbers, internet-banking passwords, PINs, or OTPs. Only use checkout links opened from an official product.
Current product catalogs and payments use Indonesian Rupiah (IDR). Available methods may differ by product and provider configuration.
Methods are not assumed to be identical across products. Checkout requests the active provider's method list and shows only available options. Serahin also retains a manual-payment route.
Serahin payment integration and Manifly billing are implemented in code. Automatic checkout remains controlled by feature flags and provider readiness. Products show the manual route or disable paid calls to action when production checks are not complete.
