What is the API trial period?

The API trial period is the limited time during which a software provider or platform lets you use its integration without paying, so you can evaluate whether it suits you before contracting it. In the WhatsApp Business world, this period is usually tied to Meta's official API (WhatsApp Cloud API) and the tools that use it, like Wando. During that time, you can connect your number, test features, and see if your conversation flow with customers improves, without spending a cent.

Why does it matter to an SME?

For an SME, the trial period is the chance to validate whether a WhatsApp tool with AI really saves time and isn't just hype. Often, buying a monthly subscription without trying it first is like throwing money away: you realize two days later that the tool doesn't understand your customers' tone or doesn't integrate with your way of working. The trial period lets you measure whether the AI suggests useful responses, whether the inbox is comfortable, and whether your salespeople will actually use it.

How is it used in practice?

In practice, the trial period starts when you create your account on a platform like Wando and activate the free trial. Usually, they don't ask for a credit card, so there's no risk of surprise charges. During those days, you connect your WhatsApp number with Meta's official API, upload your contacts or labels, and test the features: inbox with AI suggestions, templates, campaigns, statistics, multi-agent, etc. The idea is to use the time as if it were your real operation: reply to messages, create a campaign, listen to audios, and see if the tool makes your life easier.

Concrete example: an aesthetics clinic that wants to try it

Imagine you have an aesthetics clinic in Caballito. You receive 50 messages per day: appointments, prices, promotions. Without a tool, your receptionist loses hours typing responses. You activate Wando's free trial, connect the WhatsApp, and for 14 days you test: the AI suggests responses for frequently asked questions, you approve them with a click (or edit them), and you see how response time changes. You also try a campaign for customers who haven't visited in a month, with a 20% coupon on hair removal. After 10 days, you already know if it works for you: whether the AI learned from the responses you approved and proposes coherent things, or if you prefer to stay as you were. If you're not convinced, you pay nothing and that's it.

What is it confused with and how is it different?

It is confused with the 'test mode' of the WhatsApp API, which is a development environment that Meta offers for developers to test the integration without sending real messages to customers. That mode is technical: it is for programming, not for a business to evaluate a tool. A platform's trial period, on the other hand, is a commercial trial: you use the real product, with your number and your customers, but without paying the subscription. It is also confused with the 'free credits' that Meta sometimes gives to test messages: those credits are limited and run out; a tool's trial period is a time, not a quantity of messages.

Common mistakes when testing an API

• Not defining what you want to test before starting: if you don't have a goal (reduce response time, launch a campaign), the trial passes without drawing conclusions.
• Testing with a number that is not the production one: if you use a secondary number, you won't see the real customer flow and the AI won't learn from your actual conversations.
• Not involving the team that will use the tool: if only you test it and then implement it, salespeople may reject it because they don't know it.
• Skimming the tool for a day and abandoning it: the trial period works if you use it intensively, not if you go in once and look at the options.
• Not reviewing Meta's documentation on conversation limits and pricing: each country has different rates that vary over time; if you don't know them, the cost after the trial may surprise you.

What happens if you don't take the trial period into account?

If you don't take advantage of the trial period, you risk paying for a tool that doesn't fit your business. For example, you hire a flow chatbot that promises to automate everything, but then you realize that you have to program each response and that it doesn't learn from your customers. That is wasted money and time you could have used to evaluate a solution that really learns from your responses, like Wando. Also, without a trial, you don't know if the tool integrates well with your WhatsApp, if templates take long to be approved (up to 48 hours, according to Meta), or if local support responds when you need it.

How does it relate to Meta's official API?

Meta's official API (WhatsApp Cloud API) is the channel through which WhatsApp Business tools connect to your number. A platform's trial period runs on that API: that is, during the trial, the platform uses Meta's infrastructure for you to send and receive messages. Meta has its own parameters: template approval (up to 48 hours), conversation prices that vary by country, and message limits. The platform's trial period does not eliminate those limits; it only gives you time to test without paying the tool's subscription. Therefore, when evaluating a trial, it is advisable to read Meta's official documentation on prices and limits to avoid surprises later.

When does the trial period NOT apply?

The trial period does not apply if you are already using the WhatsApp API directly from your own system and you only want a tool to improve customer service: in that case, you are not testing the API, but software that connects to it. It also does not apply if you are in Meta's development mode, because there is no commercial trial there, it is a technical environment. And watch out: if the tool you choose does not have a free trial or asks for a card right away, that is a red flag. Serious platforms, like Wando, give you 14 days without a card to try it calmly.

Step-by-step setup in Wando

To start the trial period in Wando, first create your account at wando.online and choose the free 14-day trial, which does not require a card. Once inside, the key step is to connect your WhatsApp number: go to the 'Connection' section (or 'Channels') and scan the QR code that the platform shows with your WhatsApp. That links your number to Meta's official API.

Then, set up the inbox: in 'Settings' you can enable AI suggestions, set auto-response schedules, and upload templates (HSM) in the 'Templates' section. For contacts, import your list from Google Sheets or upload them manually. If you have a team, add your salespeople under 'Members' to test multi-agent. Everything is done from the panel, without touching code.

• Create account and activate free trial (14 days, no card).
• Connect WhatsApp: 'Channels' → scan QR.
• Enable AI suggestions in 'Settings'.
• Upload templates and contacts (import from Sheets).
• Add members for multi-agent.

Signs that the trial is well configured

The first sign is that messages arrive in the Wando inbox and are not left only on your phone. If you reply from the platform and the customer responds, the connection is alive. Another sign: the AI starts suggesting coherent responses after a couple of interactions; if it does not, check that you have approved messages and that the inbox is active.

If something is not working, the first thing to check is the connection with WhatsApp: unlink and scan the QR again. Then check the Meta API permissions (which you granted when connecting). If templates are not being sent, they may be under review: Meta takes up to 48 hours. And if messages are not arriving, verify that the number is verified in the Meta Business account.

How the trial changes based on business size

In a one-person business, the trial period is for validating whether the tool saves you time: you test the inbox, AI suggestions, and auto-replies outside business hours. You do not need to configure multi-agent or complex permissions.

In a fifteen-person business, the trial has another complexity: you need to configure multi-agent, define which salesperson sees which labels or contacts, and test how AI suggests responses for high volume. It is also worth evaluating statistics to see if the team responds faster. In Wando, the Enterprise plan (US$49.99/month) is designed for that size, but during the free trial you can test all features without paying.

What Meta defines and what each platform decides

Meta defines the technical limits: template approval (up to 48 hours), conversation prices (vary by country), and message policies. No platform can change that, neither Wando nor others. If you read Meta's official documentation, you will see those fixed parameters.

What is left to each platform's discretion is the trial duration, the features enabled during the trial, support, and subscription price. For example, Wando chooses to give you 14 days without a card and a 25% discount on the first month. That flexibility is part of the product, not Meta. When comparing tools, separate what is Meta's rule from what is the provider's decision.

Questions that remain after understanding the concept

Once you understand what the trial period is, second-order questions arise: does the AI learn from my responses during the trial or only after? At Wando, the AI learns from the first message you approve, so the trial period helps you see how it improves. Another one: can I migrate my number if I already use another tool? Yes, the connection is through Meta's API, so you only change the platform.

Also: what happens if I exceed Meta's message limits during the trial? Meta's limits still apply, but Wando notifies you and you can check the official documentation. And the classic one: can I extend the trial? It depends on each platform; at Wando, plans start at US$9.99/month, so if it worked for you, you can continue with the Starter plan.
