AlgoSDK Error: Forbidden

I am working on learning how to rekey addresses to create multi-sig addresses. The basic txn I am using I found in the Docs. The basic function I am using is as follows.

def rekey():
    ADDA = ""
    passphrase = ""
    ADDB = ""
    amount = 0
    params = client.suggested_params()
    txn = PaymentTxn(sender=ADDA,sp=params,receiver=ADDA,amt=amount,close_remainder_to=None,note=None,lease=None,rekey_to=ADDB)
    if passphrase:
        txinfo = sign_and_send(txn, passphrase, client)
        print("Transaction ID Confirmation: {}".format(txinfo.get("tx")))
    else:
        write_to_file([txns], "transfer.txn")

rekey()

However, I am getting an error saying the function is forbidden.

I am not sure how to read the error because it appears to have several parts or how to resolve the issue. I think it may have to do with validating the transaction with the passphrase. Additionally, I am unsure whether this will rekey the address to a single or multi-sig account. I read the docs on rekeying, but they only provide examples for goal. I have a lot of problems running goal on my machine and wanted to run the rekey transaction in Python. Any advice or suggestions would be greatly appreciated. Thank you!

Update

I checked to make sure there was Algo in the address I am using and there is 0.4 Algo. I also tried pulling the passphrase variable out of the function and then passing passphrase = None to the function. However, I received the same error.

403 usually indicates either an invalid token or an invalid URL for algod.

Can you show how you create client? (hide the token if any)
Which node are you using?

Thanks @fabrice! Here is the client creation.

algod_address = "https://mainnet-algorand.api.purestake.io/ps2"
algod_token = ""
headers = {"X-API-Key": algod_token }
client = algod.AlgodClient(algod_token,algod_address,headers)

As far as the node type, I am unable to tell based on the current node classifications in the docs. But, I think I installed the node from this GitHub repo. I also havenā€™t done anything to upgrade to a particular type of node nor have I participated in consensus from this node. My intuition is it is a non-relay node.

I changed the URL and token after checking Purestake. The new URL I changed to is below.

algod_address = "https://mainnet-algorand.api.purestake.io/idx2"

After making the change, I ran the function again and got this error.

Any thoughts or suggestions would be greatly appreciated. Thank you again!

Update

I was able to solve the connection issue with right combination of my token and URL. You were right, @fabrice - thank you!

6

Iā€™m having this same issue too. Tried test nets and mainnets for indexers and algods. Accounts have testnet tokens and real tokens. I keep getting the same 403 error.

I copied my API Key every which way, even manually typed. Can you speak more to the right combination that worked for you?

7

Please provide the source code replacing the token by xxxx

8

This was the combination that worked for me.

algod_address = "https://testnet-algorand.api.purestake.io/ps2" 
algod_token = "" 
headers = {"X-API-Key": algod_token }
algod_client = algod.AlgodClient(algod_token,algod_address,headers)
9

I am having the same issue: "Exception: Request unsuccessful: 403 (Forbidden) " , Health return succeed. but accountInfo fails every time. Can anyone help me out?

Code

            var algoApi = new AlgorandApiClient("https://mainnet-algorand.api.purestake.io/ps2");
            algoApi.SetApiKey("X-API-Key", "xxxx");
            var algoClient = new AlgodClient(algoApi);
            var version = algoClient.GetVersionAsync().Result;
            var health = algoClient.GetHealthAsync().Result;
            var accountInfo = algoClient.GetAccountInformationAsync(address).Result;
10

I am not sure what you are doing with GetHealthAsync(). But you can try this to establish the connection:

const algod_address = "" 
const algod_token = "" 
const headers = {"X-API-Key": algod_token }
const algodClient = new algosdk.Algodv2(algod_token, algod_address, headers);

If this doesnā€™t work, can you please share the complete error code. Thanks.

This is the source code I am using: https://github.com/CryptoDevTV/Algorand-
SDK/blob/master/Algorand/Algorand.Process.Algod/Client/AlgodClient.cs

Trying your suggestion.

12

Can I know which c# nuget package or github Repository URL do you mean by ā€œalgosdk.Algodv2ā€?

13

algosdk.Algodv2 is JS. Apologies I am not familiar with C#.

14

Anyway, appreciate your help, I sent an issue here for help: 403 Forbidden in the GetAccountInformationAsync() Ā· Issue #9 Ā· CryptoDevTV/Algorand-SDK Ā· GitHub

Of course. My apologies Iā€™m unable to provide additional assistance. I may also suggest providing the full text of the error, which may be helpful for debugging. ē„ä½ å„½čæ

16

I saw the issue as solved on the repo, were you able to find/fix the problem?

17

Yes, resolved.
1 Used ā€œaccountsā€ instead of ā€œaccountā€ in the URL
2 used v2 instead of v1
