Built for Encore

Billing that fits your stack

Encore's //encore:api annotations define billing endpoints with zero boilerplate. Secrets are injected at runtime — no .env files. Deploy billing to your own cloud with one command.

billing/billing.go
package billing


import (
	"context"


	commet "github.com/commet-labs/commet-go"
)


type SubscribeParams struct {
	Email      string `json:"email"`
	CustomerID string `json:"customer_id"`
}


type SubscribeResponse struct {
	CheckoutURL string `json:"checkout_url"`
}


//encore:api public method=POST path=/billing/subscribe
func Subscribe(ctx context.Context, req *SubscribeParams) (*SubscribeResponse, error) {
	client.Customers.Create(ctx, &commet.CreateCustomerParams{
		Email: req.Email,
		ID:    req.CustomerID,
	})


	sub, err := client.Subscriptions.Create(ctx, &commet.CreateSubscriptionParams{
		CustomerID: req.CustomerID,
		PlanCode:   "pro",
	})
	if err != nil {
		return nil, err
	}


	return &SubscribeResponse{
