I am trying to create a file store using API [https://api.losant.com/applications/](https://api.losant.com/applications/)/files. Once I get the AWS credentials, not sure as to how I can call the returned URL with AWS parameter file. I want to reference a file from my desktop folder. Can this be done in json body? Or is there a simpler way with an API to use the Losant AWS S3 PUT node ---

Hello @Sreyams_Jain1, > Once I get the AWS credentials, not sure as to how I can call the returned URL with AWS parameter file. Would you be able to provide more information about what URL you are referring to? How are you receiving AWS credentials? > I want to reference a file from my desktop folder. Can this be done in json body? You have a file on the desktop of your computer and are using Losant from a Web Browser, and you would like to reference that file in Losant? Do I understand this correctly? > Or is there a simpler way with an API to use the Losant AWS S3 PUT node Could you give me more information about your use case? I would love to know what you are trying to accomplish and what you would like the end solution to look like! Thank you, Heath ---

Basically when I first issue the files HTTP API , I get back the AWS credentials like below key: Content-Type: image/jpeg bucket: [files.onlosant.com](http://files.onlosant.com) X-Amz-Algorithm: AWS4-HMAC-SHA256 X-Amz-Credential: X-Amz-Date: Policy: X-Amz-Signature: “url”: “[https://s3.us-west-2.amazonaws.com/files.onlosant.com](https://s3.us-west-2.amazonaws.com/files.onlosant.com)”, “fields”: { “key”: “”, “Content-Type”: “image/jpeg”, “bucket”: “[files.onlosant.com](http://files.onlosant.com)”, “X-Amz-Algorithm”: “AWS4-HMAC-SHA256”, “X-Amz-Credential”: “”, “X-Amz-Date”: “”, “Policy”: “”, “X-Amz-Signature”: “” Next step is to upload the file in question by an HTTP API to the url with all the above and adding “file” key like file : @filepath as a form-data. The file key is not working the way I am doing. Question is there another way to do this using the AWS S3 PUT with an API and not using the node in the workflow ---

Hi @Sreyams_Jain1, Based on what you have described above, it sounds like you are trying to do one of two things: - Attempting to create a file and store it in Losant, to then push it to AWS - Pulling a file from AWS into Losant Are either of these correct? Additionally, you wrote `Basically when I first issue the files HTTP API`, could you link me to the documentation for the Files API you are utilizing? Thanks! Julia ---

Hi Julia, I am attempting to POST a file to LOSANT using api described at [https://docs.losant.com/rest-api/files/](https://docs.losant.com/rest-api/files/) This returns an AWS credentials to actually upload the contents of the file. I have difficulty in this second part when I try to do this as another HTTP call. I am not sure as to how to send the contents of the file with the file parameter. I am NOT trying to pull the file from AWS ![image001.png](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/5/52bcf967b2026e397b36a8b7f1ed6e6145de12d2.png) ![image002.png](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/7/743bc7397cae0e5650ef1620550f4b0531ac8864.png) ![image001.jpg](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/2/2485d26919316b1d80aa60f5ca8e2cb5bc0275fe.jpeg) ---

@Sreyams_Jain1, I did some searching around in the forums and found [this post](https://forums.losant.com/t/file-functionality/1017). Is what you are trying to do today different than what you were attempting in that post? Please let me know, I want to make sure we can solve your problem! Thank you, Heath ---

Yes Heath, That is correct. As in that post, I was trying to do that via javascript with form-data etc. Now, I am trying to see if I can do with a HTTP, I saw there is a AWS S3 PUT node. Is there an API way to do using that? ![image001.png](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/5/52bcf967b2026e397b36a8b7f1ed6e6145de12d2.png) ![image002.png](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/7/743bc7397cae0e5650ef1620550f4b0531ac8864.png) ![image001.jpg](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/2/2485d26919316b1d80aa60f5ca8e2cb5bc0275fe.jpeg) ---

@Sreyams_Jain1, I’m with you now! To do this, you would need to follow the instructions outlined previously. That is: 1. As you have done, request the upload from the Losant API. This returns a signed S3 URL 2. Then you would use HTTP to POST the file to that S3 URL. Please let me know if this helps. Thank you, Heath
