Okay, in the last lecture, we downloaded postman, and we were able to successfully test one of the endpoints, retrieving all the inventories from dynamodb table successfully. What we are going to do in this lecture, we are going to test create inventory endpoint. So we'll see if we are able to successfully create an inventory in dynamodb or not. So what we are going to do, we are going to create an inventory. Of course we are we can copy the previous endpoint. But also we need to configure the correct endpoint here, in this case, create and also this is a POST method again, so we'll have to change get with post.
We don't have to worry about headers and every other thing what we require here is we need to pass a request parameter. So request body in this case, and those all our JSON application data what we want to send. So what what we can do, we just copy all those JSON objects what we created a couple of lectures back, and we tested successfully with micro services we are going to, we are going to copy all those JSON objects. And we are now ready to test this endpoint. Now, let's test this endpoint. With send ups we ran into some issues here looks like we endpoint is not able to receive the parameters what we are sending across.
So what happened? So what happened in this case, let's let's examine event two And this is an opportunity to explore and understand how this works together. So let's output event. And of course, we can directly make changes. And we can test through our API endpoint. And what we are going to do is we are going to check and examine even event output.
So let's examine it has caught resource as TTP method headers. So you can of course, you can get all the details. And of course, if you remember we checked lamda proxy and that's why we are able to get all those informations here. So API gateway is passing all those information to lambda, and lambda in return is giving us all the details. What we are after here is body and body if you see body gets all the required input parameters. So what we have to do for the JSON perspective is we have to get all the data from the body property first.
And what we are going to do is we are going to create a variable request body, let's say. And since all this request body is coming as a JSON string, and we have to parse it back to use it as a JSON object, so let's parse it also suggests on top bars, and even dot body because but bodies attribute what we have found. And what we have to do is we just have to replace event with request body and that should be absolutely right. Once we have replaced everything here, let's get rid of this event. We don't want now and we are now ready to examine our create Point, let's go to dynamodb a bit and see what data we have caught at this moment. So, we have got two IDs, so two rows at this moment.
And what we are going to do is we are going to send or test this API now. So let's click on Send. And see this time it is successful. It doesn't complain anything about request body or any missing parameters. I'm going to refresh this Dynamo dB, we have caught this ID in Dynamo dB. Of course, we are not auto generating this ID we are just hard coding passed it through our request body itself.
So this is all about and I'll see you in the next lecture.
