This endpoint doesn't expect data in the URL.

Best practices

  • Use "reply_to" to maintain conversation context.

  • Handle distinct message types (text, image, video) appropriately.

  • Implement a robust retry mechanism for failed sends.

Precision Positioning: Mastering the Geographic Location Engine

Location sharing is a powerful tool for bridging the gap between the digital conversation and the physical world. Whether you are helping a customer find a brick-and-mortar store, directing a delivery rider to a precise drop-off point, or organizing a physical meetup, the /v2/send/location endpoint provides a reliable way to send interactive map pins directly into a WhatsApp chat.

🏗️ The Geolocation Pipeline: From Data to Pin

When you call the /send/location endpoint, Wawp’s engine translates raw geographic data into a rich, interactive bubble on the recipient's phone:

  1. Coordinate Verification: The engine accepts latitude and longitude as decimal strings. It validates that these coordinates fall within the valid ranges (-90 to 90 for latitude, -180 to 180 for longitude).
  2. Metadata Injection: The title and message fields are injected into the message's metadata. These don't just appear on the bubble; they are often used as the "Label" when the user clicks the pin and opens it in external apps like Google Maps or Waze.
  3. Interactive Rendering: Wawp ensures the resulting message is rendered with a clickable map thumbnail. This thumbnail is generated by the WhatsApp network based on the coordinates provided, giving the user an instant visual "Context" of the surrounding area.

🛡️ Strategic Best Practices for Geographic Data

1. Decimal Precision (The Roof-Top Rule)

For location data, precision is everything.

  • Developer Action: Use at least 6 decimal places for your coordinates (e.g., 38.893725). This level of precision is accurate to approximately 0.1 meters—the difference between a pin landing on a building's roof and landing in the middle of a busy intersection.
  • Safety: Avoid rounding coordinates in your backend, as even slight changes in the 4th decimal place can shift a location by dozens of meters.

2. Crafting Meaningful Labels

The title and message fields are your chance to provide brand clarity.

  • Title (Place Name): Use the name of the destination (e.g., "Grand Plaza Hotel - Main Entrance").
  • Message (Context/Address): Use this for the specific address or helpful hints (e.g., "1st Floor, next to the fountain").
  • UX Impact: High-quality labels reduce user anxiety and make the automated message feel deliberate and professional.

3. Static vs. Dynamic Locations

  • Static Pins: This endpoint sends a Static Pin. It represents a specific "Snapshot" in space.
  • Live Location: Note that Wawp currently focuses on static pins for high-concurrency business flows. If your use case requires a real-time moving dot (Live Location), we recommend combining static pins with regular text updates or external tracking links via /v2/send/link-preview.

🧩 Advanced Use Cases

Last-Mile Delivery Support

In a delivery app, as soon as the rider clicks "Arrived," your system can automatically send the exact location pin to the customer. This enables the customer to open the pin in their preferred navigation app to cross-verify the rider's position, drastically reducing support calls.

Geo-Fenced Personalized Offers

If your system detects a user is near a specific retail branch, you can trigger an automated "Welcome" message that includes the location pin for that exact branch. Using the reply_to parameter, you can link this location to a specific discount coupon message, creating a highly relevant "Online-to-Offline" funnel.

🛠️ Common Pitfalls and Solutions

  • Swapped Coordinates: Mixing up latitude and longitude is a common developer error that results in pins landing in the middle of the ocean. Always double-check your coordinate pairs.
  • Blank Labels: Sending a location with an empty title often results in a generic "Location" bubble. To maintain brand authority, always provide a descriptive title.
  • Coordinate Strings: Ensure you send the coordinates as strings through the API to prevent floating-point precision loss that sometimes occurs with JSON number types at high decimal counts.

Summary of Capabilities:

  • Send interactive, clickable static map pins with custom titles and addresses.
  • High-precision support for decimal coordinates (latitude/longitude).
  • Seamless integration with Google Maps, Apple Maps, and Waze for the end-user.
  • Support for complex thread-nesting via the reply_to parameter.
  • Reliable success reporting with unique message_id generation for full delivery tracking.
