The questions we get most. If yours isn't here, ask us — real humans answer.
🚀 Getting started
Getting started
How do I sign up?+
Create a free account at console.fyber.one/auth/register. We'll ask for basic business info; KYC follows when you're ready to go live.
How long does onboarding take?+
Most merchants are accepting test payments within an hour. Going live takes 2–5 business days depending on KYC verification turnaround.
Can I test before I go live?+
Yes. Test API keys are issued at signup. The /sandbox page has test card numbers and a full simulation environment.
What countries do you support?+
Today: Jamaica primarily. Cardholders can pay from anywhere; settlement to a Jamaican bank in JMD or USD.
💳 Payments
Payments
Which cards are supported?+
Visa and Mastercard, with 3D Secure 2.x. Other networks are on the roadmap.
What's the difference between authorize and capture?+
Authorize reserves funds without moving them. Capture actually moves the funds. Most merchants use auth+capture in a single call; some delay capture until shipment.
How do refunds work?+
Refund any captured payment from the dashboard or via API. Full or partial. Funds typically reach the cardholder in 3–10 business days.
What about chargebacks?+
Disputes are surfaced in the dashboard and via webhook. You have 7 days to upload evidence. See our refund policy for the full lifecycle.
🔁 Subscriptions & BNPL
Subscriptions & BNPL
Can I run subscriptions through Fyber?+
Yes. Daily, weekly, monthly, yearly, or custom cadences. Free trials, proration on plan changes, smart retry logic for failed renewals.
Do you support BNPL / installment plans?+
Yes. Configure number of installments, schedule, and retry policy. Plans persist across renewals; AI BNPL advisory recommends plan structure on Pro.
What if a recurring charge fails?+
Smart retry logic kicks in. You can configure cooldown periods, retry counts, and dunning email cadence. Pro plans include AI dispute response if a chargeback follows.
⚖️ Disputes
Disputes
How do I respond to a dispute?+
Open the dispute in the dashboard, upload evidence (receipts, delivery confirmation, customer communication). Pro merchants get an AI-generated response draft.
What's a good chargeback ratio?+
Visa monitors at 1.0%; Mastercard at 0.9%. We send proactive alerts when you approach 0.5%.
Will Fyber represent me in arbitration?+
We file the response with the issuer on your behalf using the evidence you provide. Final decision rests with the card network.
🔧 API & integration
API & integration
Where are the API docs?+
Full reference at docs.fyber.one. The /developers page on this site has quickstarts and SDK install commands.
Which SDKs are official?+
JavaScript (Node + browser), PHP, .NET, and Flutter. All published to their respective registries with semver-tracked releases.
How do I verify webhook signatures?+
Every delivery includes an X-Fyber-Signature header (HMAC-SHA256 over the body). Each SDK has a helper; the docs site shows the algorithm.
What's the rate limit?+
Per-key, per-endpoint, with separate buckets for read vs write. 429s come with Retry-After. We email well before you hit limits.
💵 Billing & settlement
Billing & settlement
When do I get paid?+
Standard settlement is T+2 (two business days) into your linked Jamaican bank account. Enterprise can negotiate faster terms.
What are Fyber's fees?+
Per-transaction processing fee disclosed at signup. No setup fees. Pro is $29/month with a 3-month free trial. See /pricing for the full breakdown.
How do I update my bank account?+
Settings → Banking → Add account. New bank accounts go through a verification step (small test deposit) before becoming the default.
Where do I see my fees?+
Every transaction itemises processor cost, GCT, and platform margin in the dashboard. Settlement statements export to CSV with the same breakdown.
