I have created an AWS Api Gateway (edge optimized) with CloudFormation. So far, everything works great. Now I´d like to make that API available under a custom domain, so I also added a custom domain resource to my CFN scripts. However, I do not see any possibility to also create an API mapping with CFN. If I create that manually, everything works fine, but I want do have it as part of the CFN scripts. I´ve seen in the documentation, that there is an ApiMapping available for Api Gateway v2 resources, but as per my understanding this does not work with edge optimized APIs. Can you help me here?
Kind regards
The BasePathMapping indeed did the trick. That was not that obvious in my opinion, since the documentation nowhere states the purpose of that resource. Thank you.

I'm developing an Android app that needs to work with an existing Amazon Web Service RDS database as well as an S3 bucket server also on AWS. My issue is that I'm struggling to find much in the way on guidance on the best approach to do so.
Currently the best thing I've found is Amazon's Amplify, the alternatives so far being SQLiteOpenHelper (seemingly unideal given that it looks to work almost exclusively with local databases, but an interesting caching option) and using Apache, which seems bad as it is extremely manual and largely deprecated.
Am I correct in then concluding Amplify is the best direction to take, or am I missing something big (it feels this way), in which case advice on how better to research this task would be immensely appreciated.
Amplify allows you to connect your app with any kind of datasource using AppSync, which is a GraphQL service managed, via resolvers that connects to anything that you want.
AppSync provides a GraphQL API including features like request and response mapping, authentication, cache and other useful things. Here you can have an overview about how it works https://aws.amazon.com/blogs/mobile/appsync-microservices/.
About how to use S3, Amplify can help with it, using amplify/cli is easy to add that resource, just running amplify add storage, as explained here https://docs.amplify.aws/lib/storage/getting-started/q/platform/android/.
I would like to build API Gateway in automated way (using some kind of framework), but I cannot find ideal solution.
The problem is that every framework is using one lambda (proxy) for entire API Gateway. I'm intrested in one API and multiple lambdas (with different persmissions and node_modules).
I was trying:
- claudiajs
- severless
- dawson
Do we have other options or I need to create it by myself via CloudFormation?
Thanks in advance!
So all Lambda's on AWS have their own execution roles, regardless of framework. Under serverless (serverless docs) you can specify a role for each Lambda by following the example in that link.
You can also individually package functions see this forum thread for more info.
I'm building an API using AWS API Gateway and AWS Lambda. I would like to achieve continuous delivery for this API. The path I've chosen to do it is to use CloudFormation through AWS CodePipeline. I've managed to to it for another project using Lambdas (without API Gateway), it works perfectly and it is really pleasant to use.
The issue I'm facing when deploying is that the Lambdas are properly updated but not the API definition. From what I understand, the AWS::ApiGateway::Deployment are immutable resources which means that for each deployment of the API I need to create a new AWS::ApiGateway::Deployment resource. This is not practical at all because for each of this AWS::ApiGateway::Deployment I have a new Invoke URL. This is not acceptable since I would have to either change my DNS record to the newly deployed API invoke URL or ask our API users to change the URL in their applications.
What I would like is to be able to change the API definition and the Lambdas implementations without my API users having to change anything in their applications.
How can I achieve this behavior?
I created a tutorial to highlight my issue. You can find it at: https://github.com/JonathanGailliez/aws-api-gateway-lambda-example

We are currently in the process of rolling out a solution which
addresses this exact problem. In the meantime, a common workaround
would be to update something small, such as a "description" field
which could then be used to "trigger" an API Gateway deployment when
updating the CloudFormation stack.
I'll update this answer and the example repo once it's rolled out.
You could run a Cloudformation update from the command line or in the AWS console. This would change the API definitions and any lambda code without changing the unique id to access your gateway.
The other option is to put your API behind a custom domain name and then you could keep deploy a new API or stage and switch over the custom domain mapping when you are ready. The users wouldn't recognize any change.
A way to achieve that is by leveraging existing frameworks like
AWS SAM
Serverless

I was able to achieve this by using CloudFormation template generated by troposphere and boto3 api in Python as follows:
Split the template into two parts
API definition, Method(s), IAM roles, ApiKey and Lambda (a)
Deployment, UsagePlan and UsagePlanKey (b)
Once changed Lambda code is zipped up and uploaded to S3 using boto3 api
Stack (b) is deleted
Stack (a) is updated with new resource id for the GET method connected to lambda
Stack (b) is created anew
Steps 3, 4, 5 are performed using CloudFormation boto3 api with blocking until completed.
Most importantly after all steps are done ApiKey value and stage Invoke URL remain the same, running updated Lambda code as tested with curl.
Note: it may take additional 30-60s for API to become fully functional after CloudFormation update is completed.
At the moment I am building various REST API's using AWS API Gateway, which is going great, but I am managing all these API's just through the WEB UI (Usual AWS Console ).
Is there a way, I can store all my API config in a source control ? So that I can keep track of the versions ? I don't want to just depend on API Gateway alone for these configurations, it will be great to have these API specifications in a source control.
Also I understand that API gateway supports swagger, that way I can store the swagger API specification somewhere. BUT I guess swagger won't cover all aspects of an API, For eg: if I am using mappings templates in API Gateway for talking to DynamoDB, how can I manage the mapping templates ?
Any thoughts ?
The question has been asked some time ago and I dont have a better answer
Hopefully, meanwhile, the serverless framework has improved a lot. It can support nodejs and python2.7 code and java should come.
serverless also supports Templates & Variables so so you can manage your dynamo resource from a Json or yaml file
Note: the aws-api-gateway already exists so feel free to use
We are using Amazon Gateway API and currently we describe API endpoints manually through the web console.
Is it possible to create definition of API in some file(s) and import it?
Why do we need this:
We want every change in the API be reviewed (it's our development process) by other people.
In case if API is deleted or broken accidently, we want to be able to restore it easily.
By now the only solution I see is to write script, based on aws apigateway command line command that creates all resources and methods.
But probably there is a better way to do it?
Thanks!
P.S. It may partially overlaps with this question: exporting api definition from AWS api gateway.
I think the Swagger Importer feature of AWS API Gateway is what you are looking for: https://aws.amazon.com/about-aws/whats-new/2015/07/introducing-swagger-importer-easily-import-swagger-api-definitions-into-amazon-api-gateway/
You can export your API definition with API Gateway extensions into swagger format. Then you use the API Gateway API importer to import/update your API.
If you are backing your API Gateway endpoints with Lambda functions you may want to check out the serverless project https://github.com/serverless/serverless
Using this framework you have a JSON file that describes your endpoints and binds them to your Lambda code in the same project structure. The tool lets you deploy the endpoints or code from the command line. It also allows you to manage other AWS resources in a CloudFormation template in the same project structure and deploy it from the command line.
