The best way to avoid provider regret is to ask hard questions before you sign, not after. Use this 20-question checklist across five areas - pricing, features, reliability, support and lock-in - to compare any WhatsApp API providers on equal terms and spot the weak ones fast.
Pricing questions
- Do you pass through Meta's per-conversation charges at cost, or add a markup?
- What is the monthly platform fee, and what does it include?
- Are there per-agent or seat fees?
- Are there setup, add-on or overage charges? See hidden costs.
Feature questions
- Do broadcasts support segmentation, scheduling and personalisation?
- Is there a no-code chatbot builder?
- Does the shared inbox support assignment, labels and multiple agents?
- Which integrations are included (store, CRM, lead sources)?
Reliability questions
- What uptime do you provide, and how do you handle webhook retries?
- Do you help manage template approvals and number quality?
- How do you handle message delivery failures?
- What is your track record at the volume I expect?
Support questions
- Is support human, and what are the response times?
- Do you provide guided onboarding and green-tick help?
- Is there help with template strategy and category selection?
- What support is included in my plan versus paid?
Lock-in questions
- Can I migrate my number to another provider later? See switching guide.
- Can I export my contacts and conversation history?
- Are templates portable or trapped in a proprietary format?
- Is there a contract lock-in or notice period?

Frequently asked questions
What should I ask before choosing a WhatsApp API provider?
Cover five areas: pricing (markups, platform and per-agent fees), features (broadcasts, chatbot, inbox, integrations), reliability (uptime, quality management), support (human, responsive, onboarding), and lock-in (migration, data export, contracts). This checklist gives 20 specific questions.
How do I compare providers fairly?
Ask every provider the same questions, score their answers, and calculate total cost at your real volume and team size. Then trial your top two so you compare real experience, not just sales claims.
What is the most overlooked question?
Whether you can leave easily - migrate your number, export data and avoid proprietary lock-in. Providers confident in their value make leaving easy, which is exactly why customers stay.
Should I sign an annual contract upfront?
Only after a successful trial and clear answers on pricing and lock-in. Prefer flexibility early; commit to longer terms once the provider has proven reliable and good value for your use case.
