Trying Twilio whatsappp api call but getting error 20422

Question

I am getting an error while using twilio whatsapp api.

Following is the code :

package main

import (
    "fmt"

    "github.com/twilio/twilio-go"
    api "github.com/twilio/twilio-go/rest/api/v2010"
)

func main() {

    clientParameter := twilio.ClientParams{}
    clientParameter.Username = "AC***********************ba"
    clientParameter.Password = "ce************************27"
    clientParameter.AccountSid = "AC************************ba"

    client := twilio.NewRestClientWithParams(clientParameter)

    params := &api.CreateMessageParams{}
    params.SetContentSid("HT**********************70")
    params.SetMessagingServiceSid("MG******************************0d")
    params.SetFrom("whatsapp:+917*******2")
    params.SetTo("whatsapp:+917********4")

    resp, err := client.Api.CreateMessage(params)
    if err != nil {
        fmt.Println(err.Error())
    } else {
        if resp.Sid != nil {
            fmt.Println(*resp.Sid)
        } else {
            fmt.Println(resp.Sid)
        }
    }
}

The error I am getting is -

Status: 400 - ApiError 20422: Invalid Parameter (null) More info: https://www.twilio.com/docs/errors/20422

Same error I am getting if trying through Postman.

Error 20422 means that one of these three conditions is not met:

• Lacking a specified Content-Type header field
• Invalid or missing XML data
• Invalid parameter type or value

The error log in the console might provide a more detailed explaination.

Since you are using the SDK, it's most likely the third bullet point. Is there a reason why you are using a MessagingServiceSid and the From field? I'd recommend updating the client to the latest version and running this script:

package main

import (
    "fmt"
    "log"
    "os"

    "github.com/joho/godotenv"
    "github.com/twilio/twilio-go"
    api "github.com/twilio/twilio-go/rest/api/v2010"
)


func main() {
    err := godotenv.Load()
    if err != nil {
            log.Fatal("Error loading .env file")
    }

    client := twilio.NewRestClient()

    params := &api.CreateMessageParams{}
    params.SetTo("whatsapp:"+os.Getenv("RECIPIENT_PHONE_NUMBER"))
    params.SetFrom(os.Getenv("TWILIO_MESSAGING_SERVICE"))
    params.SetContentSid(os.Getenv("CONTENT_SID"))

    _, err = client.Api.CreateMessage(params)
    if err != nil {
        fmt.Println(err.Error())
    } else {
        fmt.Println("Message sent successfully!")
    }
}
