Send an Image Message

In this code snippet you will see how to send a WhatsApp image message using the Messages API.

IMPORTANT: If a customer has not messaged you first, then the first time you send a message to a user, WhatsApp requires that the message contains a template. This is explained in more detail in the Understanding WhatsApp topic.


Ensure the following variables are set to your required values using any convenient method:

Key Description
NEXMO_APPLICATION_ID The ID of the application that you created.
WHATSAPP_NUMBER The WhatsApp number that has been allocated to you by Nexmo.
TO_NUMBER The phone number you are sending the message to.
IMAGE_URL The URL of the image to send.
IMAGE_CAPTION The text describing the image being sent.

NOTE: Don't use a leading + or 00 when entering a phone number, start with the country code, for example, 447700900000.


Create an application
If you do not have an application you can create one. Make sure you also configure your webhooks.

Write the code

Add the following to

Copy to Clipboard
curl -X POST \
  -H 'Authorization: Bearer '$JWT \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d $'{
    "from": { "type": "whatsapp", "number": "'$WHATSAPP_NUMBER'" },
    "to": { "type": "whatsapp", "number": "'$TO_NUMBER'" },
    "message": {
      "content": {
        "type": "image",
        "image": { 
          "url": "'$IMAGE_URL'",
          "caption": "'$IMAGE_CAPTION'"
