BHASH SMS
Think about a situation where you need to contact someone just once—like a technician or delivery agent. Storing their number permanently doesn’t make much sense. Now scale that to a business level, where thousands of messages are sent daily for promotions, updates, or support. Saving each number would be highly inefficient.
This is exactly where the WhatsApp API simplifies the process by enabling direct communication without requiring contact storage.
For businesses, this approach offers significant advantages. It streamlines communication workflows, reduces manual effort, and enables automation at scale.
Whether it’s sending order confirmations, alerts, or marketing campaigns, companies can interact with customers instantly while keeping their systems organized.
In this guide, we’ll walk you through how to leverage the WhatsApp API and other practical methods to send messages without saving contacts, helping you communicate faster, smarter, and more effectively.
Using a WhatsApp API Link
WhatsApp provides a simple yet effective way to start conversations without saving a contact, using what’s commonly known as a WhatsApp API link.
Start Chat Without Saving Contacts
This method allows you to initiate a chat instantly with any WhatsApp user, as long as you have their phone number. It is especially useful for businesses that need to send quick updates, respond to inquiries, or run campaigns without cluttering their contact list.
It eliminates the extra step of saving contacts and makes communication much faster and more efficient across both mobile and desktop devices.
WhatsApp API Link Format
https://api.whatsapp.com/send?phone=countrycodephonenumber
How It Works
- ✔ Add country code (e.g., 1 for US, 91 for India)
- ✔ Enter number without spaces or symbols
- ✔ Remove leading zero
- ✔ Works on mobile & desktop
Example
For number: 9876543210 (India)
https://api.whatsapp.com/send?phone=919876543210
Key Benefit: Instantly opens WhatsApp chat without saving the contact,
making it ideal for quick communication and business workflows.

Setting Up Default Messages
One of the most useful features of WhatsApp API and wa.me links is the ability to include pre-filled messages. This is especially valuable for businesses that want to guide conversations and maintain consistency.
By adding a predefined message, users start the conversation with the right context, making communication smoother and faster.
How It Works
Add &text= parameter to your WhatsApp link to set a default message.
Example (API Link)
https://api.whatsapp.com/send?phone=919876543210&text=Hello%20I%20am%20interested%20in%20your%20services
Example (wa.me Link)
https://wa.me/919876543210?text=Hello%20I%20am%20interested%20in%20your%20services
Note: Replace spaces with
%20 or use proper URL encoding.

Next, we’ll explore WhatsApp automation and bulk messaging techniques for scaling communication.
API Link with Pre-Filled Message
You can enhance your WhatsApp API link by adding a default message that appears
automatically when the chat opens.
This is done by including the text parameter in your link.
Format
https://api.whatsapp.com/send?phone=countrycodephonenumber&text=your%20message%20here
Make sure your message is URL-encoded, meaning spaces are replaced with %20 and
special characters are properly formatted.
Example
If you want to send a predefined welcome message to a user in the UK (country code 44) with the number 1234567890:
https://api.whatsapp.com/send?phone=441234567890&text=Hello%20and%20welcome!%20How%20can%20we%20help%20you%20today?
When someone clicks this link, WhatsApp opens with the message already typed in the chat
box,
making it easier to start the conversation instantly.
What’s Next?
Next, we’ll explore how to generate bulk WhatsApp links for campaigns and automation workflows.
wa.me Link with Pre-Filled Message
You can also include a default message in wa.me links, making it easier for users to start a conversation with pre-written text. This helps guide users on what to ask or say when they initiate a chat.
Format
https://wa.me/countrycodephonenumber?text=your%20message%20here
Just like API links, the message must be URL-encoded, where spaces are replaced with
%20 and special characters are properly formatted.
Example
Using a UK number (+44 1234567890), the wa.me link with a pre-filled message would look like:
https://wa.me/441234567890?text=Welcome%20to%20our%20service!%20How%20can%20we%20assist%20you%20today?
When users click this link, WhatsApp opens instantly with the message already typed in the
chat box,
making it quick and convenient to start the conversation.

Use Cases for Pre-Filled WhatsApp Messages
