I'm attempting to integrate a Google Chat webhook with the SNS https protocol but am having difficulty.
command1:
aws sns subscribe --topic-arn arn:aws:sns:us-east-1:123456789012:MyTopic --protocol https --notification-endpoint 'https://chat.googleapis.com/v1/spaces/AAAAaikfLEo/messages?key=<your-key>&token=<your-token>'
output:
{
"SubscriptionArn": "pending confirmation"
}
Here are the cloud monitoring logs.
{
"notification": {
"messageId": "0b72f18b-4267-4766-9196-58sckdsjwswf",
"topicArn": "arn:aws:sns:us-east-1:123456789012:MyTopic",
"timestamp": "2023-03-11 05:57:32.278"
},
"delivery": {
"deliveryId": "0b72f18b-4267-4766-9196-58sckdsjwswf",
"destination": "https://chat.googleapis.com/v1/spaces/AAAAaikfLEo/messages?key=<your-key>&token=<your-token>",
"providerResponse": "Bad Request",
"dwellTimeMs": 62,
"statusCode": 400
},
"status": "SUCCESS"
}
I tried other commands as well, but they were ineffective.
command2:
aws sns subscribe
--topic-arn arn:aws:sns:us-east-1:123456789012:MyTopic
--protocol https
--notification-endpoint 'https://chat.googleapis.com/v1/spaces/AAAAaikfLEo/messages?key=<your-key>&token=<your-token>'
--attributes '{"http":{"defaultContentEncoding":"UTF-8","headers":{"Content-Type":"application/json"}}}'
error:
Parameter validation failed:
Invalid type for parameter Attributes.http, value: OrderedDict([('defaultContentEncoding', 'UTF-8'), ('headers', OrderedDict([('Content-Type', 'application/json')]))]), type: <class 'collections.OrderedDict'>, valid types: <class 'str'>
not greeting the error in command1 but receiving no response
However, the status code in the logs is 400, so I'm not sure what the error is; it could be about the header or something else.
Is it possible to do without lambda?
Yes, if you can get to the logs of the endpoint to submit the token. Otherwise you will need some proxy that subscribes to the topic. You can host that proxy on other things besides Lambda.
